WebSince we are in a language #model setting, we pass perplexity as a metric, and we need to use the callback we just # defined. Lastly, we use mixed precision to save every bit of memory we can (and if you # have a modern GPU, it will also make training faster): learn = Learner (dls, model, loss_func= CrossEntropyLossFlat (), cbs = list ...

WebFeb 14, 2024 · GPT-2 is a direct scale-up of GPT, with more than 10X the parameters and trained on more than 10X the amount of data. GPT-2 displays a broad set of capabilities, including the ability to generate conditional synthetic text samples of unprecedented quality, where we prime the model with an input and have it generate a lengthy continuation.
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).
