Coding TRAIN WRECK: Bayesian Text Classification

Warning, this live stream was a mess and is probably unwatchable! But if you choose to continue you'll see me attempt to build a Naive Bayes text classifier from scratch in the p5.js web editor! I start by explaining the core concepts behind Bayes' Theorem (multiple times) before diving into the code. You'll see my raw, unedited process of structuring the data, implementing the algorithm, debugging issues, and finally building a simple interactive sentiment analysis demo.
