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 … The softmax function is used in various multiclass classification methods, such as multinomial logistic regression (also known as softmax regression) [1], multiclass linear discriminant analysis, naive Bayes classifiers, and artificial neural networks. Specifically, in multinomial logistic regression and linear discriminant analysis, the input to the function is the result of K distinct linear functions, and the predicted probability for the jth class given a sample vector x and a wei…
