Perplexity coherence 기준
Web책소개. The contributions to this volume investigate relations of cohesion and coherence as well as instantiations of discourse phenomena and their interaction with information structure in multilingual contexts. Some contributions concentrate on procedures to analyze cohesion and coherence from a corpus-linguistic perspective.

WebPerplexity is the measure of how well a model predicts a sample.. According to Latent Dirichlet Allocation by Blei, Ng, & Jordan, [W]e computed the perplexity of a held-out test set to evaluate the models.
