Better language models and their implications - OpenAI

By definition the perplexity (triple P) is: PP (p) = e^ (H (p)) Where H stands for chaos (Ancient Greek: χάος) or entropy. In general case we have the cross entropy: PP (p) = e^ (H (p,q)) e is the natural base of the logarithm which is how PyTorch prefers to compute the entropy and cross entropy.

Comparing BERT and GPT-2 as Language Models to …

WebPerplexity (PPL) is one of the most common metrics for evaluating language models. Before diving in, we should note that the metric applies specifically to classical language … WebA brief description talking about your rationale behind the hyperparameters used, Your perplexity scores for your model and the pretrained GPT-2 model. As a sanity check, the model should have a perplexity of less than 400. Try to achieve a number as low as possible, and there is no GPU time limit for this assignment. house for sale in baschurch
