A Ruby library implementing the ID3 algorithm for decision tree learning with support for continuous and discrete datasets.
Decision Tree is a Ruby library that implements the ID3 algorithm for building decision tree models from training data. It solves classification problems by learning rules from labeled datasets, allowing predictions on new data points. The library supports both continuous (numeric) and discrete (categorical) variables, making it adaptable to various data types.
Ruby developers and data practitioners who need a lightweight, native implementation of decision tree learning for prototyping, educational purposes, or integrating ML capabilities into Ruby applications.
Developers choose this library for its straightforward Ruby API, built-in visualization via Graphviz, and additional features like ensemble bagging and rule pruning that enhance model accuracy without external dependencies.

Provides a native Ruby implementation of ID3 algorithm, making it easy to integrate into Ruby applications without external dependencies, as shown in the straightforward example code.
Includes built-in Graphviz integration to generate graphical tree representations, aiding in analysis and debugging, as highlighted in the features section.
Handles both continuous and discrete variables seamlessly, allowing for versatile applications with different data types, evidenced by the training examples.
Offers Ruleset for pruning and Bagging trainers for ensemble learning via voting, enhancing model robustness beyond basic ID3, as described in the implementation notes.
Only implements ID3 and basic extensions like C4.5-style pruning, lacking support for modern decision tree variants or advanced ML techniques common in other libraries.
Requires Graphviz for tree visualization, adding setup complexity and potential compatibility issues, which might hinder quick prototyping.
