Naive bayesian classifierGenetic algorithms (GAs) for discovery of classification rules have gained importance due to their capability of finding global optimal solutions. However, building a rule-based classification model from large datasets using GAs is very time-consuming task. This paper proposes ...
Another useful Nave Bayes classifier is Multinomial Nave Bayes in which the features are assumed to be drawn from a simple Multinomial distribution. Such kind of Nave Bayes are most appropriate for the features that represents discrete counts. It is commonly used in text classification tasks where ...
a Naive Bayes classifier assumes that the presence of a particular feature in a class is unrelated to the presence of any other feature. For example, a fruit may be considered to be an apple if it is red, round, and about 3 inches in diameter. Even...

Thus, in the Naive Bayesian setting p(x|ω i ) can be given as MathML (27) where μ ij is an estimate for the conditional probability that feature j occurs in class ω i , and is what we are trying to estimate given a set of compounds assumed to belong to class ω i . (In...
, m), the naive Bayesian classifier adopts the “attribute conditional independence hypothesis” to calculate the class conditional probability P(ci|a) according to (1) The category marker that maximizes P(ci|a) is chosen as the classification of sample a. Since P(a) is the same for each...
In a classification problem we could, for example, learn a naive Bayesian classifier and a multi-layered neural network, store learning examples for a k-nearest neighbors algorithm, and calculate a discriminant function using the SVM method. • Hypotheses are generated by the same algorithm ...
