In 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 … Zobacz więcej Naive Bayes is a simple technique for constructing classifiers: models that assign class labels to problem instances, represented as vectors of feature values, where the class labels are drawn from some finite set. … Zobacz więcej Abstractly, naive Bayes is a conditional probability model: it assigns probabilities $${\displaystyle p(C_{k}\mid x_{1},\ldots ,x_{n})}$$ for … Zobacz więcej Person classification Problem: classify whether a given person is a male or a female based on the measured … Zobacz więcej • AODE • Bayes classifier • Bayesian spam filtering • Bayesian network • Random naive Bayes Zobacz więcej A class's prior may be calculated by assuming equiprobable classes, i.e., $${\displaystyle p(C_{k})={\frac {1}{K}}}$$, or by … Zobacz więcej Despite the fact that the far-reaching independence assumptions are often inaccurate, the naive Bayes classifier has several properties that make it surprisingly useful in practice. In particular, the decoupling of the class conditional feature distributions … Zobacz więcej • Domingos, Pedro; Pazzani, Michael (1997).
