Lecture
This lecture covers the concepts of word embeddings, including Word Embedding Models and the learning process involved. It explains how documents are mapped to term vectors and dense vectors, and how topics are distributed over terms. The instructor discusses the importance of context in determining word meaning and the process of deriving probabilities from word representations. The lecture also delves into the properties of embeddings and the learning algorithm used to create new representations. It concludes with a detailed explanation of the learning parameters and the maximization of overall probabilities in the context of word embeddings.
