<abstract>State-of-the-art language models perform well on a variety of language tasks, but they continue to struggle with understanding negation cues in tasks like natural language inference (NLI). Inspired by Hossain et al.

We also introduce a new learning strategy for negation building on ELECTRA’s (Clark et al., 2020) replaced token detection objective.
