This is one of the best video I enjoyed ever while learning machine learning. Explaining conditional probability to naive Bayes demo in detailed and still in concise way is art. Wow, this is excellent playlist.

I think When we are using Naive Bayes for text classification, it calculates probabilities at the token level rather than for intact words. For example, at 10:52 when considering the word "vaccine", the model is actually looking at the likelihood of the token "vaccine" rather than the exact word. This is an important distinction, because tokenizing the input texts allows the model to handle different word forms, capture useful n-gram contexts, and focus on predictive tokens. So the probabilities are calculated for tokens P(token|class) rather than unique words P(word|class). Tokenization before applying Naive Bayes is a key step, as it allows the model to better capture patterns and meaning from the input texts. Correct me if I am wrong
