WebJan 7, 2024 · This criterion combines log_softmax and nll_loss in a single function. For numerical stability it is better to "absorb" the softmax into the loss function and not to explicitly compute it by the model. This is quite a common practice having the model outputs "raw" predictions (aka "logits") and then letting the loss (aka criterion) do the ... 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)
