Bayesian classifier in data mining

Data Mining Bayesian Classifiers In numerous applications, the connection between the attribute set and the class variable is non- deterministic. In other words, we can say the class label of a test record cant be assumed with certainty even though its attribute set is

    Jul 04, 2021 Bayes’ Theorem is named after Thomas Bayes. He first makes use of conditional probability to provide an algorithm which uses evidence to calculate limits on an unknown parameter. Bayes’ Theorem has two types of probabilities : Prior Probability [P (H)] Posterior Probability [P (H/X)] Where, X – X is a data tuple. H – H is some Hypothesis

    Jan 20, 2015 Bayesian inference, of which the na ve Bayes classifier is a particularly simple example, is based on the Bayes rule that relates conditional and marginal probabilities. There are two major approaches in applying Bayesian inference to the classification task: model-probability inference and class-probability inference

    Apr 28, 2013 It allows scientists to combine new data with their existing knowledge or expertise. A Naive Bayes classifier would suggest that it is most likely going to rain tomorrow. Bayesian rule’s emphasis on prior probability makes it better suited to be applied in a wide range of scenarios. Consider the following comic that I obtained from xkcd: Two

    May 05, 2018 Naive Bayes algorithms are mostly used in sentiment analysis, spam filtering, recommendation systems etc. They are fast and easy to implement but their biggest disadvantage is that the requirement of predictors to be independent. In most of the real life cases, the predictors are dependent, this hinders the performance of the classifier
