Introduction:- In this article, we’ll talk about why Vector Space Models became popular in NLP realm. Then we’ll take deep dive into Word2vec Model. As we all know that Machine learning models take vectors or arrays of numbers as input. When we work on the text data, we can not give words directly to the …

Introduction In this article, we’ll talk about CBOW(Continuous Bag of words ) Model ,and how does this model works internally. CBOW is a variant of the word2vec model predicts the center word from (bag of) context words. So given all the words in the context window (excluding the middle one), CBOW would tell us the most …

Introduction In this article, we’ll talk about what is Word2Vec Model ,different types of it. Then we’ll understand SkipGram Model architecture in more detail. “You should know a word by the company it keeps.” The Word2Vec technique is based on a feed-forward, fully connected architecture. To give an overview of word2vec algorithm ,let’s train a …
