Binary classification naive bayes
WebApr 10, 2024 · In binary Naive Bayes, since we increase each event (item being from 0 or 1 ) by 1 you have to change denominator to N + 1 × 2. In general, we denote α > 0 as smoothing (psuedocounting) factor. THen your smoothed probability becomes, P r s m o o t h e d ( y = i x) = 1 y = i + α N + α × d WebIn statistics, naive Bayes classifiers are a family of simple "probabilistic classifiers" based on applying Bayes' theorem with strong (naive) independence assumptions between the features (see Bayes classifier).They are among the simplest Bayesian network models, but coupled with kernel density estimation, they can achieve high accuracy levels..

WebMay 7, 2024 · Naive Bayes is a classification algorithm that is suitable for binary and multiclass classification. It is a supervised classification technique used to classify future objects by assigning class labels to instances/records using conditional probability. In supervised classification, training data is already labeled with a class.
