Low perplexity language model
Web11 apr. 2024 · Perplexity, on the other hand, is a measure of how well a language model predicts the next word in a sequence. It is an indication of the uncertainty of a model when generating text. In the context of AI and human writing, high perplexity means the text is more unpredictable and diverse, while low perplexity indicates a more predictable and … Web23 dec. 2024 · The word likely is important, because unlike a simple metric like prediction accuracy, lower perplexity isn’t guaranteed to translate into better model performance, …
