Pros: Extremely fast to train/apply and is reliably a high bias/low variance classifier (less likely to overfit). Handles extraneous features well, meaning it's robust to irrelevant features. Famously good at text classification. e.g. spam filtering.

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 ... WebbNaive Bayes – pros and cons.

Webb11 apr. 2024 · Aman Kharwal. April 11, 2024. Machine Learning. In Machine Learning, Naive Bayes is an algorithm that uses probabilities to make predictions. It is used for classification problems, where the goal is to predict the class an input belongs to. So, if you are new to Machine Learning and want to know how the Naive Bayes algorithm works, … WebbIn a small text classification problem I was looking at, Naive Bayes has been exhibiting a performance similar to or greater than an SVM and I was very confused. I was wondering what factors decide the triumph of one algorithm over the other. Are there situations where there is no point in using Naive Bayes over SVMs?
