WebNov 28, 2024 · Therefore, with torch.exp () function, we can get the perplexity. When training, the inputs put into the model are input_ids, token_type_ids, and labels. The GPT-2 LM Head Model gives an output … WebOur largest model, GPT-2, is a 1.5B parameter Transformer that achieves state of the art results on 7 out of 8 tested language modeling datasets in a zero-shot setting but still underfits WebText. Samples from the model reflect these improvements and contain coherent paragraphs of text.
WebThe compromise is that they use a stride length of 512. Using smaller stride lengths gives much lower perplexity scores (although I don't fully understand why?). It seems that in practice most papers use a stride length which is just equal to the max sequence length of the model (so 1024 for GPT-2). What's the consensus here? WebFeb 6, 2024 · Intro. The fastai library simplifies training fast and accurate neural nets using modern best practices. See the fastai website to get started. The library is based on research into deep learning best practices undertaken at fast.ai, and includes “out of the box” support for vision, text, tabular, and collab (collaborative filtering) models.
WebNov 28, 2024 · The perplexity is an evaluation method for LM which indicates how the model chooses the next tokens with high probabilities. This is calculated by normalizing … WebOct 28, 2024 · You can upload your custom model on Hugging Face’s Model Hub⁸ to make it accessible to the public.

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.
