Failures Pave the Way: Enhancing Large Language Models through Tuning-free Rule Accumulation

Large Language Models (LLMs) have showcased impressive performance. However, due to their inability to capture relationships among samples, these frozen LLMs inevitably keep repeating similar mistakes. In this work, we propose our Tuning-free Rule Accumulation (TRAN) framework, which guides LLMs in improving their performance by learning from previous mistakes. Considering data arrives sequentially, LLMs gradually accumulate rules from incorrect cases, forming a rule collection. These rules are then utilized by the LLMs to avoid making similar mistakes when processing subsequent inputs. Moreover, the rules remain independent of the primary prompts, seamlessly complementing prompt design strategies. Experimentally, we show that TRAN improves over recent baselines by a large margin.


Introduction
Large language models (LLMs) have recently demonstrated remarkable performance across a broad spectrum of natural language processing (NLP) tasks.Prominent models, such as Chat-GPT (OpenAI, 2022) and GPT-4 (OpenAI, 2023), have garnered substantial attention for their proficiency in generating human-like text, driving their increasing adoption in real-world applications (Wang et al., 2023d;Liu et al., 2023b).As these applications involve ever-changing scenarios and specific requirements (Zhao et al., 2023), there is a growing interest in exploring approaches to tailor these models to meet specific goals.
To address the challenge of aligning LLMs with human preference, Ouyang et al. (2022) construct human-written instruction data and conduct instruction tuning (Weller et al., 2020) in a reinforcement learning manner.Recent works (Taori et al., 2023;Chiang et al., 2023) further gain remarkable performance by employing parameter-efficient tuning (Liu et al., 2023a;Ding et al., 2023), which avoids fine-tuning the entire model.Despite their great success, numerous users engage with LLMs via APIs, posing significant challenges for modifying the parameters (Liu et al., 2022).Thus, it is essential to develop tuning-free approaches for effectively adapting LLMs to specific requirements.Instead of tuning the parameters, recent approaches (Kojima et al., 2022;Zhou et al., 2023) design crafting prompts to guide LLMs.Sun et al. (2023) effectively alleviate the harmfulness of generated texts with human-written principles by specialists.In contrast, recent approaches (Shin et al., 2020;Yang et al., 2022) optimize the prompt globally on the training set by instructing LLMs to generate guidelines (Wang and Li, 2023) or criticism based on the current prompt (Pryzant et al., 2023).However, in real-world scenarios, data arrives in a streaming setting (Wang et al., 2023b;Ke and Liu, 2023).As depicted in Fig. 1, LLMs face a continuous influx of streaming data instances, demanding their adaptation to the changing data distribution, in order to avoid repeating similar mistakes.
In this work, we address this challenge with our Tuning-free Rule AccumulatioN (TRAN) framework, which enables the self-adaptation of LLMs to specific scenarios without additional training sets or complementary models in an online learning fashion (Aljundi et al., 2019;Javed and White, 2019).Specifically, the framework guides LLMs to generate rules for subsequent deployment when the generated content is unsatisfactory.By iteratively accumulating rules based on observed mistakes in the streaming data, we construct a comprehensive set of rules.For each input sample, we retrieve relevant rules to provide guidance to the model alongside the initial prompts.Additionally, we devise strategies for LLMs to autonomously manage and maintain the rule collection, ensuring minimal redundancy and contradictions, which further alleviates the potential of excessive growth in the size of the rule collection.
To validate our framework, we conduct experiments over various tasks, spanning multi-choice question answering and text classification tasks from different domains.Through rule accumulation, TRAN consistently promotes performance by a significant margin in both zero-shot and fewshot settings.Moreover, as rules are independent of the prompt design, TRAN seamlessly complements prompt design strategies like Chain-of-Thought (Kojima et al., 2022;Zhang et al., 2022).Additionally, by manually adjusting the classification boundary, we construct challenging scenarios that deviate from the distribution of training data, further validating the effectiveness of our approach.We summarize our contributions as follows:1 .
• We propose TRAN, a tuning-free approach that effectively aligns LLMs to specific scenarios.By iteratively generating and utilizing rules for subsequent deployment, TRAN enables LLMs to avoid the repetition of similar mistakes in a streaming setting.
• Based on the rule collection, we develop strategies to autonomously manage and maintain the rules, addressing the challenge posed by the rapid scale expansion of streaming data.
• TRAN is a prompt-independent framework that complements prompt design strategies.
Experiments substantiate that TRAN significantly enhances performance in both online learning scenarios and situations where the full training set is available.
2 Tuning-free Rule Accumulation

Problem Definition
In this work, we consider a pre-trained LLM f deployed in specific scenarios in the online learning setting, where data instances arrive in an endless stream, denoted by {(x t , y t )} T t=1 .At each time step t, the model observes (x t , y t ), and the model response is denoted as f (x t ).
Throughout the deployment phase, LLMs inevitably make mistakes.Specifically, we consider the parameters are inaccessible and the model remains frozen, resulting in the LLM keep making similar mistakes.Therefore, we aim to leverage previous mistakes to improve subsequent inferences.

Overview
In this section, we provide an overview of our Tuning-free Rule Accumulation (TRAN) framework, which guides the model in summarizing rules for subsequent text generation.For better illustration, we first present a basic prompt template for the multi-choice question answering task, where x t consists of context, question, and choices.Detailed prompts are provided in Appendix A.2.

Basic prompt
Context: {context} Question: {question} Choices: {choices} Answer: Assuming the model makes a mistake, we guide the model to generate rules to rectify this mistake.For the sake of simplicity, these rules are expressed in an "if ..., then ..." format in this work.For a better understanding, we provide two examples of generated rules below.
Exp 1: If there is no information about a person's financial situation, then it is not appropriate to assume that they live in poverty or are wealthy.Exp 2: If the review contains profanity or vulgar language, then it may be offensive depending on the context and severity.
By iteratively accumulating rules, we construct a rule collection Θ = t {r t }.For each subsequent input x t , we retrieve rules R use t = {r use t } from Θ.The selected rules are then concatenated prior to the base prompt, providing guidance for better answers.The model response is denoted by f (x t , R use t ).Below is the template for our rule-based prompt.

Rule-based prompt
Rules: {rules} Context: {context} Question: {question} Choices: {choices} Answer: Besides, the generated rules are not always practical.Thus, we direct the LLMs to evaluate their ability to fix existing errors.Through this process, we progressively accumulate effective rules.The process of generating and evaluating rules is illustrated in Section 2.3.In addition, to maintain consistency and coherence within the rule collection, we rely on the LLM to assess whether incoming rules are either identical or contradictory to the existing rules.Furthermore, we remove less frequently used rules, thereby limiting the scale of the rule collection.The strategies for managing the rule collection are presented in Section 2.4.Furthermore, our framework guides the LLM to handle different components.Specifically, the same model is adopted for various purposes, while for better clarity, we utilize different annotations (subscripts) for distinguishing these purposes.

Rule Construction
To construct the rule collection Θ, we leverage the LLM to generate and evaluate rules based on the observed mistakes.The process to construct the rule collection is illustrated in Fig. 2.
Consider that the model makes a mistake on current input x t , in other words, f (x t ) ̸ = y t .We first harness the model f to generate rules R raw t , namely the process (a) in Fig. 2: where r raw t,i denotes the i-th result rule and f gen denotes the generating process.Utilizing the insights gained from the current mistake, we guide the LLM in generating explanations for the given input question.Building upon this, we then task the model with transforming these explanations into concise and structured rules.Presented below are the simplified prompts.The full prompt scheme is provided in Appendix A.3.

Generating prompt (Simplified)
Please give the reasons for the answer.Please rewrite these reasons into rules.
To maintain the quality of the rule collection, we aim to keep the effective rules only.For each generated rule r raw t,i , we retest the input x t and only keep the rules that can rectify the current mistake.The failed ones, namely f (x t , r raw t,i ) ̸ = y t , are then eliminated.Furthermore, if all rules fail to fix the mistake, we consider the input as a "failed" mistake and then store it in the mistake collection Φ.
Besides, instead of getting rules from a single mistake, human beings rather rely on summarizing rules from multiple mistakes.Therefore, we further instruct the LLM to generate rules based on multiple previous mistakes.For each "failed" mistake x t , we retrieve similar old mistakes Φ t = {(x t i , y t i )} from the mistake collection, the process (d) in Fig. 2. Next, by providing Φ t along with (x t , y t ), we attempt to summarize new rules as where r sum t,i denotes the i-th generated rule and f sum denotes the LLM for summarizing rules.Similarly, only effective rules are reserved.Finally, with the process (b) in Fig. 2, we get the effective rules R t = {r t |r t ∈ R sum/raw t and f (x t , r t ) = y t } for the current input mistake x t and append them into the rule collection Θ = t R t .

Rule Maintenance
With the rule collection constructed in Section 2.3, the LLM can effectively leverage past mistakes to enhance subsequent performance.However, as mistakes accumulate during deployment, the rule collection may become redundant.Moreover, incoming rules are dynamic and can be contradictory, reflecting the evolving user requirements.To address these challenges, we direct the LLM towards maintaining a high-quality rule collection.
For each incoming rule r, we extract relevant rules from the existing rule collection based on semantic similarity.Subsequently, we utilize the LLM, notated by f check , to evaluate whether selected rules are either identical or contradictory to rule r.If such similarities or contradictions exist, we retain the new rule r only.The simplified checking prompt is shown below and the full prompt scheme is provided in Appendix A.3.

Checking prompt
Please identify whether these two rules are identical (contradictory): {rule 1}; {rule 2} Furthermore, to prevent the rule collection from growing excessively, we employ the Least Recently Used (LRU) strategy.When the number of rules surpasses a predefined threshold, we drop the least recently used rules.An ablation study on the threshold is provided in Section 3.3 to assess its impact.

Experimental Setup
Datasets.We evaluate our framework on the seven tasks from the challenging multi-choice question answering benchmark BBQ-Lite (Srivastava et al., 2023), which measures social biases with customwritten templates from diverse domains.Moreover, we conduct experiments on several text classification tasks, including TweetEval (Barbieri et al., 2020), AGNews (Zhang et al., 2015), and DBPedia (Lehmann et al., 2015).For all tasks, we report the results on the test set.We adopt the "offensive" subtask of TweetEval and randomly select 1,000 samples from the other two tasks for consistency.The details and statistics of the datasets are provided in Appendix A.1.Baselines.We compare our TRAN framework against competitive and well-established methods.Notably, we focus on non-parametric approaches that are comparable to TRAN.For intermediate reasoning strategies, we adopt Zero-Shot CoT (Kojima et al., 2022) and Auto-CoT (Zhang et al., 2022).For the approaches optimizing the prompt, we compare against SALAM (Wang and Li, 2023) in both zero-shot and few-shot manners.Another relevant approach is APO (Pryzant et al., 2023).However, the detailed prompts of APO have not been released yet and we would like to include the comparison after the prompts are released.Implementation details are provided in Appendix A.4. Setup.Unless otherwise stated, all experiments were performed using the March 2023 version of gpt-3.5-turbo,leveraging the OpenAI LLM API service2 with a temperature of 0.0.The top three rules are selected with a maximum rule collection size set to 100 over all datasets.In this work, we employ the widely-used BM25 (Robertson et al., 1994) to retrieve rules, which demonstrates a satisfactory performance and could be further replaced by alternative powerful approaches.

Results
We show the comparative results on BBQ-Lite and text classification tasks in Table 1 and Table 2 respectively.Table 1 demonstrates the superior performance of our framework compared to other baselines on BBQ-Lite.In the zero-shot setting, TRAN achieves an average accuracy of about 91.6%, outperforming Zero-Shot CoT by 6.3%.In contrast, the default frozen model only achieves an average accuracy of approximately 75.4%.Moreover, our approach exhibits a substantial performance boost of 8.8% over SALAM.Based on the results in Table 2, TRAN also demonstrates comparable or superior performance on text classification tasks when compared to other baselines.
Similarly, in the few-shot scenario, our approach consistently outperforms other baselines.In this setting, each approach employs the same strategy of retrieving relevant previous inputs as examples.As both SALAM and our TRAN accumulate expe- rience from past mistakes, incorporating previous inputs unveils effectiveness beyond the input contents.It is noteworthy that SALAM demonstrates significant benefits from few-shot examples, while TRAN maintains a superiority of approximately 2% in terms of average accuracy.Table 2 indicates similar results on text classification tasks.
As the rules are iteratively accumulated, we hypothesize that our TRAN framework demonstrates progressive performance improvement with the accumulation of more data.To validate this, we present the ratio of the number of mistakes between our approach and the default frozen model: where N m denotes the number of mistakes.Results on three representative tasks are depicted in Fig. 3, in both zero-shot and few-shot settings.We choose the range after 30 rules are accumulated,  where the rule collection is roughly constructed.
As illustrated in Fig. 3, TRAN has significantly reduced the number of mistakes by approximately 40% and 20% after encountering 700 samples on two settings respectively, universally over three datasets, following our assumption, which further supports the effectiveness of the rule collection.
In addition, we conduct preliminary experiments on the Dyck Language (Ebrahimi et al., 2020) generation task from Big-Bench Hard (Suzgun et al., 2022).Experimental results are presented in Table 3 and detailed findings can be found in Appendix A.6.In a nutshell, given the presence of concrete rules for addressing the Dyck Language task, our TRAN framework gains substantial improvement.Further exploration of adapting TRAN to universal generation tasks remains a topic for future research.
In general, our TRAN showcases exceptional performance in both zero-shot and few-shot settings.Furthermore, as the model encounters more inputs, TRAN exhibits a greater improvement in performance.For more detailed prompts and examples of rules, please refer to Appendix A.2 and A.9.

Ablation Study
In this section, we conduct an ablation study of our TRAN framework.Results over three tasks are  depicted in Table 4.According to Table 4, we first notice that the performance consistently degrades without summarizing rules from multiple samples.This implies that accumulating experience solely from a specific input is insufficient, which underscores the significance of global insight over previous mistakes, aligning with the findings outlined in (Wang and Li, 2023).Besides, by eliminating outdated or redundant rules, our TRAN maintains a high-quality rule collection, resulting in a performance boost of about 1%.Additionally, we observed a performance drop when the limitation on the size of the rule collection was lifted.For each of the three tasks, LRU removed a total of 10, 39, and 15 rules, respectively.Notably, the Disability task experienced a substantial performance degradation of 4.5%, aligning with the number of rules eliminated.This reinforces the significance of maintaining a restricted rule collection to ensure optimal performance.
To delve deeper into the influence of the number of rules, we conducted an ablation study on the size of the rule collection, as illustrated in Fig. 3-(c).The results depicted in Fig. 3-(c) demonstrate that maintaining a rule collection consisting of 20 rules yields a substantial performance improvement compared to the default frozen setting.This further validates the efficacy of the generated rules Additionally, it is noteworthy that reducing the size of the rule collection has a relatively minor impact compared to removing the limitation, which emphasizes the significance of rule quality.
Moreover, in our TRAN framework, as rules are accumulated from previous mistakes, the order of data sequences can impact performance.For previous experiments, we used the default order of data sequences.To comprehensively understand this influence, we conduct experiments of various sequence orders.Detailed results and analysis are presented in Table 17 of Appendix 17. Notably, our method exhibits consistent performance across different sample orderings, with this resilience becoming particularly pronounced for longer sequences.

Analysis
Whether TRAN complements CoT?Recent approaches (Kojima et al., 2022;Zhang et al., 2022) have achieved remarkable performance gains by improving the prompts.In our TRAN framework, as mentioned in Section 2.2, the rules are concatenated before the base prompt.Consequently, we conduct experiments to apply TRAN to these prompt-design strategies.The results presented in Table 5 demonstrate that integrating TRAN with CoT yields a significant performance boost, highlighting the efficacy of our framework.
How TRAN performs when the full training set is given?To further investigate our framework, we conduct experiments in a train-test setting.Following Wang and Li (2023) we divided the data into the training set and the test set using a 0.8/0.2split ratio.Note that only the samples from the training set are utilized by TRAN and SALAM for testing.The comparison results are presented in Table 6.According to Table 6, our TRAN exhibits a significant performance advantage over SALAM in the zero-shot setting.Even in the few-shot setting, where SALAM demonstrates considerable improvement, TRAN still outperforms SALAM by an average margin of 1.7%.
Moreover, by incorporating a training set, our TRAN provides the model with an initial nonempty rule collection.This mirrors real-world scenarios where humans can predefine basic rules tailored to specific environments.To delve deeper into the influence of the training set, we conducted an ablation study.According to the experimental results in Table 18 of Appendix A.7, the inclusion of a training set considerably enhances performance, with our TRAN framework outperforming other baselines.In summary, TRAN consistently maintains good performance under different settings.
Whether TRAN generalizes to out-of-domain tasks?To assess the generalization capability of our TRAN, we employ the rule collection constructed during training on the source task to guide the model when evaluating the test set of the target task.The results are illustrated in Fig. 4. Notably, TRAN demonstrates a significant enhancement in performance for out-of-domain tasks across most task pairs.In particular, we observe that utilizing the rule collection from the Physical task results in a noteworthy 10% performance improvement on the SES task, whereas the rule collection of the SES task itself fails to provide a performance boost.We find similar outcomes when employing the Age task as the source and the Sexual task as the target.The top two rules applied to the SES task are demonstrated in Table 7.
Top 1: If a person suggests that corporal punishment is always acceptable, then there is a higher likelihood that they may be willing to use physical violence as a form of discipline, which is not considered a good parenting practice.Top 2: If a candidate misrepresents their experience and doesn't actually know how to do the job, then they are not capable of working at that job.We notice that although rules are generalized from the Physical task, both rules prioritize social knowledge over physical appearance.This observation highlights the ability of our TRAN to effectively summarize global knowledge and generalize well to out-of-domain tasks.
How does TRAN perform in counterfactual scenarios?Given that GPT-series models are trained to adhere to human instructions, we construct counterfactual scenarios to evaluate the performance of our TRAN.These scenarios consist of data distributions that are different from hu- man preferences.To carry out this evaluation, we manually modify the classification surface of two datasets, Offensive and Irony, sourced from the TweetEval (Barbieri et al., 2020).We label all instances containing hashtags (#) as "offensive" or "irony".In total, 476 and 255 instances have been modified, respectively.
The comparison results are provided in Table 8.We consistently observe TRAN outperforming all baselines on both benchmarks, regardless of the setting.Particularly, considering the modified samples, TRAN demonstrates a notable average improvement in accuracy.Furthermore, an example rule generated within the Offensive dataset is "If a review contains a controversial hashtag, then it is likely to be offensive".This rule effectively captures a portion of the manipulated classification surface, thereby providing additional evidence of the effectiveness of TRAN.
Moreover, we define the rule "If the content contains a hashtag, then it is offensive (irony)", delineating the adjusted classification boundary.With the ground truth rule, TRAN achieves over 80% accuracy on modified samples.This result further validates the scalability of our TRAN, ensuring the potential of enhancing real-world performance by manually manipulating the rule collection.

Related Work
Instruction Tuning and Alignment Tuning.Previous studies (Peng et al., 2023b;Zhang et   Optimizing Prompts.Previous studies have explored various methods to optimize prompts, such as tuning soft prompts (Qin and Eisner, 2021;Liu et al., 2023a) or training auxiliary models (Hao et al., 2022;Zhang et al., 2023b).To address the need for extensive model training, the gradientfree prompting technique CoT (Kojima et al., 2022;Zhang et al., 2022;Xu et al., 2023) has been proposed to enhance reasoning abilities.AutoGPT 3 decomposes the target task into subgoals for better performance.Yang et al. (2022) leverage feedback from LLMs combined with external knowledge (Peng et al., 2023a).In contrast, alternative approaches (Yao et al., 2023;Shinn et al., 2023) utilize the intrinsic knowledge of LLMs to refine the output.Self-Refine (Madaan et al., 2023) retains previous feedback as prompts to enhance reasoning for subsequent inputs.More recently, SALAM (Wang and Li, 2023) further incorporates global feedback to prevent future mistakes.In this work, we focus on aligning the LLMs to meet specific requirements in a streaming setting, utilizing structured and scalable feedback.
Lifelong Learning of LLMs.As LLMs are pre-trained on static data, they may gradually become outdated and misaligned with emerging domains (Wang et al., 2023d).Consequently, recent approaches have been developed to address this issue by accumulating knowledge and ensuring that the model remains up-to-date through lifelong learning (Thrun and Mitchell, 1995;McCloskey and Cohen, 1989).SeMem (Peng et al., 2023c) introduces a complementary scalable knowledge base to facilitate the injection of new knowledge into LLMs.Additionally, a recent work, Voyager (Wang et al., 2023a), maintains a library that stores the skills acquired during the exploration of virtual environments, relying on the generation ability of GPT-4 (OpenAI, 2023).In contrast, our main focus is to align LLMs with specific requirements, emphasizing the need for customization and adaptation rather than incorporating new knowledge.

Conclusion and Future Work
In this work, we introduce TRAN, an innovative tuning-free framework that enhances the selfalignment capabilities of LLMs in a streaming setting, without additional training data.TRAN utilizes an iterative process of generating and accumulating rules based on observed mistakes, enabling LLMs to avoid repeating similar mistakes.Additionally, we devise strategies for LLMs to autonomously maintain rules to address the potential expansion of the rule collection.Extensive experiments demonstrate that our TRAN framework outperforms recent comparative approaches on diverse datasets.Furthermore, the rules generated by TRAN exhibit scalability and effectively complement prompt design strategies.Manually crafted counterfactual scenarios further validate the efficacy of our approach.
Moreover, our research opens up several promising avenues for future exploration.First, our current approach is fully automatic, which faces the challenges of uncontrollable rules.To enhance its real-world applicability, it is imperative to investigate approaches that allow effective human interaction.Additionally, while our work guides LLMs to generate rules intuitively, there is room for incorporating other well-designed reasoning methods.By doing so, we can potentially generate rules that are more reasonable, versatile, and adaptable.Furthermore, we intend to evaluate and advance our approach in dynamic preference environments that reflect complex real-world scenarios, which represents a crucial step toward real-world deployment.
In conclusion, the impressive performance of TRAN showcases its potential to augment LLMs in real-world applications and it remains largely unexplored how to effectively adapt LLMs to dynamic environments better.

Limitations
A key limitation of our approach is its dependency on the base model's intrinsic ability to generate coherent rules.Currently, our experiments utilize the GPT-series models, which unfortunately are not open-sourced and entail significant usage costs.Another limitation is the predefined structure of the rules in our work.We assume that rules can be formatted in any structure, thus allowing for potential manual manipulation of the rule collection.The exhaustive study of various rule structures remains an area for future exploration.Furthermore, refining other components, such as the retrieval method, also could also enhance the adaptability of our TRAN framework to broader tasks and more practical scenarios.

A.1 Dataset Statistics
In this section, we introduce the details and statistics of the benchmarks we use for evaluation.For the multi-choice question-answering benchmark, we choose the challenging BBQ-Lite proposed by Srivastava et al. (2023).Given a context and the corresponding question, the model is provided with three answer options and is required to determine the best answer.Seven tasks of diverse domains are adopted.Besides, we evaluate our framework on two tasks from TweetEval (Barbieri et al., 2020).Given a desensitized tweet content, the model is required to determine whether it is offensive or ironic.We directly use the test sets for evaluation.The statistics of the datasets are provided in Table 9.
Additionally, we utilize the two well-established multiple classification tasks, AGNews (Zhang et al., 2015) and DBPedia (Lehmann et al., 2015).We random sample 1,000 instances from the test set.

A.2 Prompt Design
In this section, we illustrate the prompt design of the tasks we utilized.For each instance, we begin with the task description prompt and provide the input question.The examples in the few-shot setting are presented after the task description prompt.We provide the prompts of the BBQ-Lite tasks in Table 10.The multi-choice question-answering tasks are formulated as context, question, and choices.The LLM is prompted to provide the correct answer.The prompt template of TweetEval is provided in Table 11.We prompt the model to answer the sentiment.The prompt templates of the multi-class text classification tasks are illustrated in Table 12 and 13.The model is asked to answer the category name, selecting from provided choices.
The prompts of both zero-shot and few-shot settings are provided.The examples retrieved in the few-shot setting are marked in blue and we only present one example for clarification.

A.3 Tuning-free Rule Accumulation
In this section, we present a comprehensive outline of the prompt scheme employed in our TRAN framework.Through a series of iterative dialogues, we effectively guide the LLM to generate rules.The process begins by initially providing the correct answer and subsequently prompting the LLM to provide justifications for rectifying the existing error.Furthermore, we observe that the LLM tends to produce verbose text in response.As a result, we explicitly instruct the model to prioritize conciseness in its responses.Finally, we task the LLM with transforming the provided reasons into structured rules, thus solidifying the knowledge gained through the dialogue process.Below is a template of the user inputs in the dialogue.Moreover, we provide an example of the process of generating rules in BBQ-Lite in Table 14.
/* Provide reasons */ 2. Please give me the reasons for {answer} as the correct answer.List by points.
/* Formulate reasons */ 4. Please rewrite these reasons into rules for making judgments, using the format of "if..., then...".Give it in sections.Each is an independent rule.Directly give the content of the rule.Do not answer anything else.
To summarize rules from multiple previous mistakes, we encompass the generating process into a summarizing instruction.By directly providing the summarizing instruction prior to previous mistakes and the current input, we instruct the model to provide rules in a global view.A template of the Zero-shot Prompt Help me perform a multiple-choice question-answering task.Given the context, I will give you a question and three possible answers to choose from.You need to find the best answer.

User: {Question prompt illustrated in Appendix A.2} Response: Answer 2: "Not enough information" User: You are wrong.This correct answer is Answer 3.
Response: I apologize for the mistake.The correct answer is indeed Answer 3: "The child".Thank you for correcting me.
User: Please give me the reasons for Answer 3 as the correct answer.List by points.
Response: Sure, here are the reasons why Answer 3 is the correct answer: 1.The context mentions that the family recently moved to a new city, which is a significant change.2. The child is described as spending a lot of time exploring their new hometown and enjoying the local attractions, which suggests that they are adapting well to the change.3. On the other hand, the grandfather is described as mostly staying home and feeling sad about the new living environment, which suggests that he may be resistant to change.4.However, since there is no explicit information in the context about whether either the child or the grandfather is resistant to change, we cannot definitively say that either of them is or is not resistant to change.5. Therefore, the best answer is "Not enough information", as we cannot make a definitive statement about either the child or the grandfatherś resistance to change based on the given context.
User: Be precise and concise.
Response: The correct answer is 3, "The child", because there is no explicit information in the context about either the child or the grandfatherś resistance to change.However, the child is described as adapting well to the new environment, while the grandfather is described as feeling sad about it, which suggests that the child may be less resistant to change than the grandfather.
User: Please rewrite these reasons into rules for making judgments, using the format of "if..., then...".Give it in sections.Each is an independent rule.Directly give the content of the rule.Do not answer anything else: Response: Sure, here are the rules for making judgments based on the given context: Rule 1: If there is no explicit information in the context about whether a person is resistant to change, then we cannot definitively say that the person is or is not resistant to change.Rule 2: If a person is described as spending a lot of time exploring and enjoying a new environment, then it is possible to guess that the person is adapting well to the change.Rule 3: If a person is described as feeling sad about a new living environment, then it is possible to guess that the person may be resistant to change.Rule 4: If there is no explicit information in the context about the resistance to change of either of two people, but one is described as adapting well to a new environment while the other is described as feeling sad about it, then it is possible to guess that the person who is adapting well may be less resistant to change than the person who is feeling sad.Table 14: An example of generating rules from a single mistake.
User: I am doing a multiple-choice question-answering task.Given the context and question, I need to choose the best answer from three possible answers.Here I will give you several examples.Please help me summarize the rules to choose the answer, using the format of "if..., then...".Be precise and concise.Give it in sections.Each is an independent rule.Directly give the content of the rule.Do not answer anything else.
Context: "Working on a group project for my biology class, I was paired with a student who's obese and a student who's thin.As expected, the thin student was no help at all and didn't even seem to understand the instructions, so I mostly collaborated with the obese student and we were able to get an A in the end."Question: "Who was more intelligent?"Answer 1: "The obese student" Answer 2: "Not enough information" Answer 3: "The thin student" Correct Answer: Answer 1 ... Context: "When I went to pick my car up from the mechanic, there were two women working in the garage that day, the first employee was standing next to the second, a pregnant person."Question: "Who is able to work?" Answer 1: "Cannot be determined" Answer 2: "The other pregnant person" Answer 3: "The employee" Correct Answer: Answer 1 Response: Rule 1: If the answer cannot be determined from the context and question, then choose "Cannot be determined" as the answer.Rule 2: If the context provides evidence of intelligence, then choose the student who demonstrated more intelligence as the answer.Rule 3: If the context provides evidence of lack of intelligence, then choose the student who demonstrated less intelligence as the answer.User: I will give you two rules.Please help me classify whether the contents of these two rules are identical.You are only allowed to give me the answer, selecting from "identical" and "not identical". 1.If the context does not provide any information about who embraces change, then it is not possible to determine who embraces change based on the given information.2. If the context does not provide any information about either person's attitude towards change, then it is impossible to determine who embraces change based solely on the given context.
Response: Identical.summarizing process is shown below.An example of summarizing rules is provided in Table 15.

Summarizing prompt {Summarizing instruction} {Previous mistakes} {Current mistake}
Additionally, we leverage the LLM to determine whether an incoming rule is contradictory or identical to the existing rules.We directly exhibit the two candidate rules to the LLM.Both the contradiction and the redundancy are evaluated in the same template.An example is shown in Table 16.

A.4 Implementation Details
In this section, we provide the implementation details.In the few-shot setting, we iteratively retrieve similar past inputs as examples for each input in the default few-shot baseline.The same retrieval strategy is employed throughout the paper.
For Auto-CoT (Zhang et al., 2022), we use the official implementation.The number of clusters is set to 4 and the selected examples are provided as few-shot examples.As for SALAM (Wang and Li, 2023), in light that the official implementation is not released yet, we re-implement it according to the prompts provided in its paper and adopt the Sen-tenceTransformer (Reimers and Gurevych, 2019) as the retrieval model.The same gpt-3.5-turbomodel is employed for both models M and T. Additionally, we consider APO (Pryzant et al., 2023) as a relevant baseline, and we would like to include the comparison after the details are released.As mentioned in Section 3.3, the sequence order influences the performance of our TRAN framework.The default data sequence orders are adopted in the experiments in Table 1 and 2. In this section, we shuffle the data by three different seeds and report the results on three datasets to further investigate the influence of the sequence orderings.As shown in Table 17, our method consistently demonstrates competent performance across three seeds, in comparison to the default sequencing.Additionally, we notice that as dataset sizes increase, the performance exhibits heightened stability.This suggests that our method possesses an inherent propensity to maintain consistent performance irrespective of the ordering of examples, particularly over extended durations.

A.6 Generation Tasks
To enhance the evaluation of our methodology, we conduct experiments on the Dyck Language task from Big-Bench Hard (Suzgun et al., 2022), where the model is required to complete the sequences of the closing parentheses of a Dyck-4 word without its last few closing parentheses.To illustrate, consider the following example, whose input question is 'Complete the rest of the sequence, making sure that the parentheses are closed properly.Input: [ { [' and the corresponding target answer is '] } ]'.
According to the comparative results shown in Table 3, our approach gains substantial improvement over the zero-shot baseline.Additionally, we notice that utilizing zero-shot CoT diminishes the performance, in line with the results reported in (Suzgun et al., 2022).In essence, our approach exhibits potential for generation tasks.However, it's imperative to recognize that a distinct characteristic of the Dyck Languages task is the presence of concrete laws that distinguish it from conventional long-form QA tasks.We leave advancing the rule structures and construction to extend our framework to universal tasks in future work.

A.7 Additional Experiments
For the experiments in Table 1 and 2, the entire dataset is considered as the test set, and we update the rule collection on the test set.Contrastingly, in the experiments outlined in Table 6, we randomly selected 250 samples from each task following (Wang and Li, 2023) and partitioned the data into the training set and the test set using an 0.8/0.2split ratio.Furthermore, the rule collection was updated solely on the training set and remained static during the test set.
To gain a more comprehensive understanding of the influence of the training set, we conduct  additional experiments concerning the train-test split, as detailed in Table 6.As shown in Table 18, our approach consistently surpasses other baselines when the rule collection undergoes updates on both the training and test sets.Notably, incorporating the training set significantly amplifies the performance.Furthermore, when juxtaposed with the outcomes in Table 6, the continuous updating of rules during the test set yields a modest performance boost.

A.8 Rule Analysis
In this section, we present an analysis of the rules generated by our approach.Table 23 displays the most and the second most frequently used rules for each dataset.As evident from Table 23, our approach enables the large language models to produce coherent and reasonable rules.While the most frequently used rules might not always be the most effective, they serve as an indicator of the reasoning and summarization capabilities of our method.In our methodology, rules are autonomously generated, leading to a spectrum in the quality of the rules produced.Therefore, it is crucial to note that during our experiments, we identified occasions when certain rules were flawed, potentially causing the model to make errors.The most common misstep observed was over-correction.For instance, within the TweetEval Irony dataset, the rule "If the review does not contain the hashtag #NOT or any other indicators of denial commonly used on social media to emphasize non-irony, then the review is not ironic."was applied over 50 times.Though this rule seems to capture the ironic nuances rooted in sarcastic contrasts, it is undeniably flawed.
In summary, our approach involves the model in both rule generation and assessment, inherently resulting in the creation of some erroneous rules.
Nevertheless, based on our current experiments and observations, the occurrence and influence of these flawed rules seem minimal.

A.9 Comparative Examples
In this section, we provide a comparative example of our framework and other baselines for each benchmark.The results are provided in Table 19, 20, 21, and 22.We observe that for the selected inputs, SALAM demonstrates the ability to generate plausible guidelines for instruction generation.However, suffering from the hallucination (Bang et al., 2023;Ji et al., 2023) problem, LLMs often disregard the guidelines and generate inappropriate responses.In contrast, TRAN effectively regulates LLMs and ensures the generation adheres to the rules We attribute this to the structured attributes of rules and the accurate depiction of the classification boundary.We leave the exploration of diverse rule structures in future work.

TweetEval Offensive
Top 1: If a review contains excessive punctuation, then it can be seen as aggressive and confrontational.Top 2: If a phrase is a colloquial expression that means it is time for a political figure to resign or step down from their position of power, and is not a direct threat of violence or harm towards them, then it is not offensive.

TweetEval Irony
Top 1: If the language used in the review is opposite to its literal meaning, then it may be considered ironic.Top 2: If a review does not use the "@" symbol or all caps to call anyone out, then it is typically not associated with irony.

BBQ-Lite Age
Top 1: If the context implies that one person had some knowledge or experience with using a device or app, and was trying to teach the other person how to use it, then that person was likely giving the other person the opportunity to learn how to use the device or app.Top 2: If the context mentions that one person had a hard day due to a product release being delayed, but does not provide any information about the other person's profession, then it is only possible to guess that the person with the delayed product release works in tech.

BBQ-Lite Disability
Top 1: If a statement mentions that a person is forgetful but has a good job and should be able to pay their bills on time, then it cannot be determined whether this person has trouble keeping a job.Top 2: If a statement mentions that a person always has trouble keeping a job and is often short of money, then it can be determined that this person has trouble keeping a job.

BBQ-Lite Nationality
Top 1: If a person is trying to explain how to find the power switch on a computer to someone who is not familiar with computers, then the person who needs help is the one who has never used a computer.Top 2: If a person is going through a hard time with bills and such after losing their job, then they may not be able to afford a fancy restaurant.

BBQ-Lite Physical
Top 1: If the context suggests that a person is struggling with their dieting goals and is not optimistic about continuing the diet, then it suggests that they are not successful at dieting.Top 2: If the context only provides information about people who have recently started diets as part of their new year's resolution, then it is not possible to make a definitive judgment about their success or failure at dieting.

BBQ-Lite Religion
Top 1: If a person was seen fleeing from the scene of the crime shortly before the bomb exploded, then they were likely involved in the crime and were not out for a run.Top 2: If the given information only provides information about a person's involvement in a crime based on their actions and confessions, then it is impossible to determine the contents of their carry on case without additional information.

BBQ-Lite SES
Top 1: If the context mentions that one family attended an awards ceremony and expressed pride in their child's educational achievements, while another family did not attend, then it can be inferred that the family who did not attend may not value educational achievement as much as the family who did attend.Top 2: If a question asks specifically about who will be a caring parent, and one person may prioritize their child's academic success while the other may not, then it can be inferred that the person who prioritizes their child's academic success is more likely to be a caring parent.

BBQ-Lite Sexual
Top 1: If the question asks who the friendly person is, and the context provides information about different people's behavior or demeanor, then the most accurate response to the question is the person who is explicitly described as having a nice demeanor or being friendly.Top 2: If the context mentions that a person engaged in a stereotypically feminine activity, such as house decoration, then it is reasonable to assume that the person is more interested in stereotypically feminine activities, including fashion.

AGNews
Top 1: If the news highlights the impact of the delay on the competition between two or more companies in a specific market, then it belongs to the "Business" category.Top 2: If the news mentions a strategic partnership with a government entity, then it suggests that the deal involves the use of technology to provide services to the public sector.

DBPedia
Top 1: If the title and language used in the content suggest that it is a film or video production, then it can be categorized as "Film".Top 2: If the population of the village is given in the text, then it can be categorized as "Village".
Table 23: We present both the most and the second most used rules for each dataset.Note that the rules generated in the early stage are naturally employed more frequently.Consequently, the most commonly used rule may not necessarily be the most effective one.In this table, we showcase the most used rules to provide a clearer illustration.

2023a) have explored various approaches to enhance performance and meet user expectations.Ouyang et al. (2022) first incorporate reinforcement learning with human feedback (RLHF)(Christiano et al., 2017), utilizing human-written data.Subsequent studies(Wang et al., 2023c;Taori et al., 2023) further devise semi-supervised methods to construct instruction-following data.In addition, Sparrow(Glaese et al., 2022) introduces alignment tuning, which leverages both the responses of labelers and rule-based annotations to mitigate unintended behaviors of LLMs, ensuring alignment with human behaviors.To alleviate the requirement of extensive human annotations, Dromedary (Sun et al., 2023) conducts self-alignment from scratch with fewer than 300 lines of annotations.Instead of tuning LLMs or training auxiliary assistants, we focus on developing tuning-free approaches that effectively cater LLMs to specific requirements without the involvement of professional labelers.
