T softmax

WebThe softmax function extends this thought into a multiclass classification world. It assigns decimal probabilities to every class included in a multiclass problem. Since each of them would lie between 0 and 1, the decimal probabilities must add up to 1. Softmax finds application in several subjects, including multiclass neural networks.
