Hierarchy softmax

WebNet lexical reference system to help define the hierarchy of word classes. 2 PROBABILISTIC NEURAL LANGUAGE MODEL The objective is to estimate the joint probability of se-quences of words and we do it throughthe estimation of the conditional probability of the next word (the target word) given a few previous words (the context): … WebHierarchical softmax. In hierarchical softmax, instead of mapping each output vector to its corresponding word, we consider the output vector as a form of binary tree. Refer to the structure of hierarchical softmax in Figure 6.34: So, here, the output vector is not making a prediction about how probable the word is, but it is making a ...
