Semi-naive bayesian classifier
WebThe Hierarchical Redundancy Eliminated Tree Augmented Naïve Bayes (HRE-TAN) classifier is a semi-naïve Bayesian model that learns a type of hierarchical redundancy-free tree-like feature representation to estimate data distributions. In this work, we propose two new types of positive feature values prioritized hierarchical redundancy eliminated tree augmented … WebOct 15, 2024 · Semi-Naive Bayesian Classifiers (SNBC) SNBC is based on relaxing independence assumptions. 2 Note that using MDL – aka minimal description length score – (or any other ‘generic’ scoring functions) in order to learning general Bayesian networks usually result in poor classifiers

WebRecent work in supervised learning has shown that a surprisingly simple Bayesian classifier with strong assumptions of independence among features, called naive Bayes, is competitive with state-of-the-art classifiers such as C4.5. This fact raises the question of whether a classifier with less restrictive assumptions can perform even better. In this …
