"Webarchical Softmax is called the two-level tree, which uses O(p N) classes as the intermediate level of the tree, with the words as the leaves [5,13], but deeper trees have also been explored [15]. Hierarchical softmax is fast during training, but can be more expensive to compute during test-ing than the normal softmax [4]. However, it is nonetheless " - Hierarchical softmax的作用
