Latent Dirichlet Allocation - Part 1
Offered By: Serrano.Academy via YouTube
Course Description
Overview
Dive into the first part of a two-video series exploring Latent Dirichlet Allocation (LDA), a powerful machine learning technique for sorting documents by topic. Learn about the problem LDA addresses, understand the concept of a document-generating machine, and explore the blueprint for the LDA model. Discover how to calculate document probabilities, grasp the idea of distribution of distributions, and visualize topics in multiple dimensions. Engage with interactive quizzes to reinforce your understanding of topic placement and selection. Uncover the intricacies of Dirichlet distributions and their role in LDA. Explore the process of finding optimal settings for the LDA model and identifying winning arrangements. This 27-minute video provides a comprehensive introduction to LDA, setting the stage for the second part of the series.
