How does Naïve Bayes relate to probabilistic independence relaxation methods?

Relaxed Naïve Bayes models weaken independence assumptions using feature grouping or dependency modeling.

Standard NB assumes strict conditional independence. Relaxed variants group correlated features or introduce dependency structures like tree-Augmented Naïve Bayes (TAN), which allows limited dependencies between features while maintaining tractable inference. This improves performance on structured data.
