Fasttext threshold
WebMar 22, 2024 · fastText provides two models for computing word representations: skipgram and cbow ('continuous-bag-of-words'). The skipgram model learns to predict a target word thanks to a nearby word. On the other hand, the cbow model predicts the target word according to its context. The context is represented as a bag of the words contained in a … WebMar 4, 2024 · Multi-class classification using fastText. ...
