WebOct 15, 2024 · There are two main approaches for learning word embedding, both relying on the contextual knowledge. Count-based: The first one is unsupervised, based on matrix factorization of a global word co-occurrence matrix. Raw co-occurrence counts do not work well, so we want to do smart things on top. Context-based: The second approach is …
