Bear is a free and open source machine learning system that I have developed as a personal hobby since 2008.
Bear finds statistically significant dependencies between variables to build piecewise constant models.
It then models the residuals of each model with other similar models, and continues to build complex models.
Bear is similar to decision trees and random forests, but with a different philosophy and algorithm.
Its frequentist approach automatically avoids overfitting. It learns efficiently without needing neural networks.
Bear won’t “replace” existing ML or AI systems. It’s a machine learning engine that can be dropped into existing systems.
A quick guide to building and running my free and open source ANSI C implementation of Bear is here.
These Bear pages describe personal hobby research that I have undertaken since 2008.
