62. Naive Bayes: Fast, Simple, Surprisingly Effective

Your email spam filter makes a decision in milliseconds. Thousands of words. Instant classification. Most of the algorithms we've covered so far would struggle with that. KNN needs to compute distances across thousands of features. SVM slows down on high dimensions. Even tree-based models take time. Naive Bayes does it in one pass. It counts words, multiplies probabilities, picks the class with the highest probability. Done. It's been doing this since the 1990s and it still works. What You'll Le
