WebJul 22, 2024 · The words need to be made meaningful for machine learning or deep learning algorithms. Therefore, they must be expressed numerically. Algorithms such as One Hot Encoding, TF-IDF, Word2Vec, FastText enable words to be expressed mathematically as word embedding techniques used to solve such problems. Web>>> model2 = FastText (vector_size=4, window=3, min_count=1, sentences=common_texts, epochs=10) The two models above are instantiated differently, but behave identically.
