Rethinking softmax cross entropy loss
WebWe first formally show that the softmax cross-entropy (SCE) loss and its variants convey inappropriate supervisory signals, which encourage the learned feature points to spread … WebMay 2, 2016 · In contrast, cross entropy is the number of bits we'll need if we encode symbols from using the wrong tool . This consists of encoding the -th symbol using bits instead of bits. We of course still take the expected value to the true distribution , since it's the distribution that truly generates the symbols: Cross entropy is always larger than ...
