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 logistic function to multiple dimensions, and used in multinomial logistic regression. The softmax function is … 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 … See more Smooth arg max The name "softmax" is misleading; the function is not a smooth maximum (a smooth approximation to the maximum function), but is rather a smooth approximation to the arg max function: the function whose … See more Geometrically the softmax function maps the vector space $${\displaystyle \mathbb {R} ^{K}}$$ to the boundary of the standard $${\displaystyle (K-1)}$$-simplex, cutting the dimension by … 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 where the "4" was in the original input. This is what the function is normally used for: to highlight the largest values and suppress … See more The softmax function is used in various multiclass classification methods, such as multinomial logistic regression (also known as softmax regression) [1], multiclass 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 … See more The softmax function was used in statistical mechanics as the Boltzmann distribution in the foundational paper Boltzmann (1868), … See more WebSep 17, 2024 · The value function measures the goodness of the state ...
