Sklearn bayesian classifier
Webb11 apr. 2012 · scikit-learn has an implementation of multinomial naive Bayes, which is the right variant of naive Bayes in this situation. A support vector machine (SVM) would probably work better, though. As Ken pointed out in the comments, NLTK has a nice wrapper for scikit-learn classifiers.

WebbWe achieved 83.5% accuracy. Let’s see if we can do better with a linear support vector machine (SVM), which is widely regarded as one of the best text classification algorithms (although it’s also a bit slower than naïve Bayes). We can change the learner by simply plugging a different classifier object into our pipeline: Webb28 mars 2024 · Naive Bayes classifiers are a collection of classification algorithms based on Bayes’ Theorem. It is not a single algorithm but a family of algorithms where all of them share a common principle, i.e. …
