WebGPT-2 is a transformers model pretrained on a very large corpus of English data in a self-supervised fashion. This means it was pretrained on the raw texts only, with no humans labelling them in any way (which is why it can use lots of publicly available data) with an automatic process to generate inputs and labels from those texts.

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.
