This means that (assuming float32 ), you'll need 4 * 300 * 10M * 2 bytes = 24 GB just to store the parameters and the gradient for the output layer. Hierarchical Softmax (HSM) doesn't reduce the memory requirements - it just speeds up the training.

Hierarchical Softmax Explained Papers With Code

WebHierarchical Softmax is a is an alternative to softmax that is faster to evaluate: it is $O\left(\log{n}\right)$ time to evaluate compared to $O\left(n\right)$ for softmax. It utilises a multi-layer binary tree, where the probability of a word is calculated through the … 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 WebHierarchical softmax is a softmax alternative to the full softmax used in language modeling when the corpus is large.

Web13 de dez. de 2024 · Typically, Softmax is used in the final layer of a neural network to get a probability distribution for output classes. But the main problem with Softmax is that it is computationally expensive for large scale data sets with large number of possible outputs. To approximate class probability efficiently on such large scale data sets we can use … 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).
