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 … See more The softmax function, also known as softargmax or normalized exponential function, converts a vector of K real numbers into a probability distribution of K possible outcomes. It is a generalization of the See more The softmax function takes as input a vector z of K real numbers, and normalizes it into a probability distribution consisting of K probabilities proportional to the exponentials of the input numbers. That is, prior to applying softmax, some vector components could … See more In neural network applications, the number K of possible outcomes is often large, e.g. in case of neural language models that predict the most likely outcome out of a vocabulary which … See more If we take an input of [1, 2, 3, 4, 1, 2, 3], the softmax of that is [0.024, 0.064, 0.175, 0.475, 0.024, 0.064, 0.175]. The output has most of its weight … See more Smooth arg max The name "softmax" is misleading; the function is not a smooth maximum (a smooth approximation to … See more Geometrically the softmax function maps the vector space $${\displaystyle \mathbb {R} ^{K}}$$ to the boundary of the standard $${\displaystyle (K-1)}$$-simplex See more The softmax function was used in statistical mechanics as the Boltzmann distribution in the foundational paper Boltzmann (1868), formalized and popularized in the influential textbook Gibbs (1902).
