Gini Index based sparse signal recovery algorithm

The complete Python code for the Attribute Selection Algorithm, using the parameters Entropy, Information gain and Gini Index. The following code will help in induction of the Decision Tree using a custom data set present in CSV format.

A Python-powered ML toolkit featuring a Decision Tree builder and Naive Bayes classifier implemented from scratch. Supports attribute selection using Entropy (ID3) and Gini Index (CART), with custom metric calculations, recursive tree construction, and Graphviz-based visualization for decision boundaries and probabilistic classification.

The objective of this work is to provide tools to be used for the classification of ordinal categorical distributions. To demonstrate how to do it, we propose an Homogeneity (HI) and Location (LI) Index to measure the concentration and central value of an ordinal categorical distribution.
