WebMay 1, 2024 · Gumbel-Top Trick 5 minute read How to vectorize sampling from a discrete distribution. If you work with libraries such as NumPy, Jax Tensorflow, or PyTorch you (should) end-up writing a lot of vectorization code: instead of using control-flow operations (e.g. for loops), you write code that operates on an entire set of values at once. . Inputs … WebSep 9, 2024 · To my understanding, I think these two methods are different. For example, we have a tensor a = tensor ( [0.0000, 0.5000, 0.0000, 0.0000, 0.7000]), if I only want the top 2 softmax result for this tensor, the result should be tensor ( [0.0000, 0.4502, 0.0000, 0.0000, 0.5498]), but if I apply nn.Softmax () first and set the values I don’t want ... WebMar 1, 2024 · Fan et. al (2024) introduced a simple, but very powerful sampling scheme, called Top-K sampling. In Top-K sampling, the K most likely next words are filtered and the probability mass is redistributed among only those K next words. GPT2 adopted this sampling scheme, which was one of the reasons for its success in story generation. the oakridge school my backpack
