Witryna30 kwi 2024 · The Naive Bayes Algorithm is a classification method based on the so-called Bayes Theorem. In essence, it assumes that the occurrence of a feature is … 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. There is not a single algorithm for training such classifiers, but a family of algorithms based on a … Zobacz więcej 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 … Zobacz więcej Abstractly, naive Bayes is a conditional probability model: it assigns probabilities $${\displaystyle p(C_{k}\mid x_{1},\ldots ,x_{n})}$$ for each of the K possible outcomes or … 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).
