Word2Vec and Word Embeddings for Natural Language Processing

In the world of artificial intelligence, text data must be translated into numbers that computers can understand. This course introduces you to the core concepts of word embeddings, focusing on how Word2Vec revolutionized the way machines process human language. You will learn how to convert raw text into dense vectors that capture semantic relationships, meaning, and context. By the end of this course, you will understand how to represent textual information mathematically and build foundational vector spaces for modern language models. What you'll learn: Understand the difference between sparse representations like one-hot encoding and dense word embeddings; Learn the underlying mechanics of the Continuous Bag of Words (CBOW) and Skip-gram architectures; Practice calculating word similarities and semantic relationships using mathematical distance formulas; Explore advanced optimization techniques including negative sampling and hierarchical softmax; Apply modern preprocessing pipelines and tokenization practices to prepare text for training. The course begins with foundational concepts in natural language processing and vector mathematics before guiding you step-by-step through the architecture, training, and evaluation of Word2Vec models. This text-based program is designed for beginners, software developers, and aspiring data scientists with basic Python knowledge and no prior machine learning experience.
