Hierarchy softmax
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 ... WebTo illustrate this strategy, consider the hierarchy in Figure 1(b), ... The categorical cross-entropy loss after softmax activation is the method of choice for classification. 2.

In order to reduce the time for model training, people have invented some optimization algorithms, such as Noise Contrastive Estimation, to approximate the conventional softmax but run much …
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). Web27 de jan. de 2024 · Jan 27, 2024.
