WebUnlike word2vec, FastText also learn vectors for sub-parts of words called character n-grams ensuring that e.g., the words “የህዝብን”, “የህዝብ”,” ህዝብ” and “ህዝብን” all fall into same dimension in vector space, even if they tend to appear in different contexts. WebApr 1, 2024 · And when you do, you have the option of simply using FastText in its base unsupervised mode – as a way to featurize text – then pass those FastText-modeled features to some other explicit classifier option (such as the many calssifiers in scikit-learn with .fit () methods).
