Optimal Sparse Decision Tree code:

Fast Sparse Decision Tree Optimization via Reference Ensembles
(code) | (paper)

Creates optimal sparse decision trees quickly. Remember not to remove the regularization term! The predecessor to this algorithm is OSDT.

Sparse Generalized Additive Models code

Fast Sparse Generalized Linear and Additive Classification
(code) | (paper)

Produces sparse additive models quickly.

Learning Optimized Risk Scores from Large-Scale Datasets (RiskSLIM)
(code) | (paper)

Creates risk assessment scoring systems, which are linear models with integer coefficients that estimate risk. Note that this code is slow and is being replaced shortly. Use the code above instead for now.

Supersparse Linear Integer Models (SLIM)
(matlab code) | (python code) | (matlab code) | (paper) | (bib)

For building scoring systems, which are linear models with integer coefficients. Part of winning entry for 2016 INFORMS Innovative Applications in Analytics Award. Note that this code is slow and is being replaced shortly. Please use the Fast Sparse GAM code above.

Rule Lists and Falling Rule Lists

Certifiably Optimal RulE ListS (CORELS)
(code) | (R-bindings by Dirk Eddelbuettel) (paper)

For classification, an alternative to decision trees. Predecessors to this code are Bayesian Rule Lists (BRL) and Scalable Bayesian Rule Lists (SBRL) (R interface, C code - Creative Commons License). The CORELS code is more efficient, so please use that.

Optimized Falling Rule Lists and Softly Falling Rule Lists
(paper) | (code) | (bib)

For classification where the probabilities decrease along the list.

Falling Rule Lists (FRL)
(python code) | (paper) | (bib)

For classification where the probabilities decrease along the list. This algorithm is Bayesian, based on sampling. The one above uses optimization.
