Mastering Word Embedding Models: Word2Vec, GloVe, and fastText Demystified
Certainly! Word embedding models are a type of natural language processing technique that represents words as dense vectors in a continuous vector space. These representations capture semantic relationships between words, making them useful for various NLP tasks. Here's an overview of three popular word embedding models: Word2Vec, GloVe, and fastText. Word2Vec: Word2Vec was introduced by Tomas Mikolov and his colleagues at Google in 2013. It offers two training algorithms: Continuous Bag of Words (CBOW) and Skip-gram. Both algorithms learn to predict context words given a target word or vice versa. Continuous Bag of Words (CBOW): This algorithm predicts a target word based on its context words. It uses a sliding window approach to create training samples. Skip-gram: Skip-gram, on the other hand, predicts context words from a target word. It aims to learn better representations for infrequent words. Word2Vec embeddings are learned through a shallow neural network, where the wei
