WebAll about the SOFTMAX function in machine learning! Webtree. A prominent example of such label tree model is hierarchical softmax (HSM) (Morin & Bengio, 2005), often used with neural networks to speed up computations in multi-class classification with large output spaces. For example, it is commonly applied in natural language processing problems such as language modeling (Mikolov et al., 2013).
