WebJun 7, 2024 · On their dataset of choice (WebText, which GPT-2 was trained on), they find a perplexity of 12.4. But, crucially, they find that, while their model is capable of generating text with much lower perplexity (1.5!), the generated text is either repetitive or incoherent. Staying closer to human perplexity is better! This last point is very important. WebThe smaller the stride, the more context the model will have in making each prediction, and the better the reported perplexity will typically be. When we run the above with stride = 1024, i.e. no overlap, the resulting PPL is 19.64, which is about the same as the 19.93 reported …
