Pytorch output probability
WebThis function is useful in statistics where the calculated probabilities of events may be so small as to exceed the range of normal floating point numbers. In such cases the logarithm of the calculated probability is stored. This function …

WebIt should be clear that the output is a probability distribution: each element is non-negative and the sum over all components is 1. You could also think of it as just applying an element-wise exponentiation operator to the input to make everything non-negative and then dividing by the normalization constant.
