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 ...

Error in Calculating Sentence Perplexity for GPT-2 model …
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. 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. 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.
