Softmax Activation Function: Everything You Need to Know

WebJan 18, 2024 · # Softmax applies the exponential function to each element, and normalizes # by dividing by the sum of all these exponentials # -> squashes the output to be between 0 and 1 = probability # sum of all probabilities is 1: def softmax(x): return np.exp(x) / np.sum(np.exp(x), axis=0) x = np.array([2.0, 1.0, 0.1]) outputs = softmax(x) WebAug 16, 2024 · 1 Answer. Sorted by: 3. You have two classes, which means the maximum target label is 1 not 2 because the classes are indexed from 0. You essentially have to subtract 1 to your labels tensor, such that class n°1 is assigned the value 0, and class n°2 value 1. In turn the labels of the batch you printed would look like: flanshaw hotel https://nextdoorteam.com
