WebJul 13, 2024 · By creating a word vector from subword vectors, FastText makes it possible to exploit the morphological information and to create word embeddings, even for words never seen during the training. In FastText, each word, w, is represented as a bag of character n-grams. WebThis allows FastText to capture information about subword units, such as prefixes and suffixes, which can be useful for handling out-of-vocabulary words and morphologically rich languages.
