Abstract
We discuss the strategies and results of a small-sized training program based on Italian child-directed speech (less than 3M tokens) for various network architectures. The rationale behind these experiments [1] lies in the attempt to understand the effect of this naturalistic training diet on different models architecture. Preliminary findings lead us to conclude that (a) different tokenization strategies produce only numerical, but not statistically significant, improvements overall, although segmentation aligns more or less with linguistic intuitions; and (b) modified LSTM networks with a single layer and a structurally more controlled cell state perform worse in training (compared to standard one- and two-layered LSTM models) but better on linguistically critical contrasts. This suggests that standard loss/accuracy metrics in autoregressive training procedures are linguistically irrelevant and, more generally, misleading, since the best-trained models qualify as poorer “linguistic theories” ([2], pace [3]).
