Hierarchical softmax的作用
http://cs231n.stanford.edu/reports/2024/pdfs/130.pdf WebHierarchical softmax. Computing the softmax is expensive because for each target word, we have to compute the denominator to obtain the normalized probability. However, the denominator is the sum of the inner product between the hidden layer output vector, h, and the output embedding, W, of every word in the vocabulary, V. To solve this problem ...

The recently introduced continuous Skip … WebWeighted output matrix (WO) with dimensions FxN. We multiply one hot vector 1xN with WI and get a neurone 1xF. Then we multiply the neurone with WO and get an output vector 1xN. We apply softmax function and choose the highest entry (probability) in the vector. Question: how is this illustrated when using the Hierarchical Softmax model?
