Generative vs. Discriminative Models by Dr. Roi Yehoshua

WebbMultinomial Naive Bayes (MNB) is better at snippets. MNB is stronger for snippets than for longer documents. While (Ng and Jordan, 2002) showed that NB is better than SVM/logistic regression (LR) with few training cases, MNB is also better with short documents. SVM usually beats NB when it has more than 30–50 training cases, we show that MNB ...
