smac: Sparse Multi-category Angle-Based Large-Margin Classifiers
Version 1.0

This package provides a solution path for L1-penalized angle-based classification. Three loss functions are implemented in smac, including the deviance loss in logistic regression, the exponential loss in boosting, and the proximal support vector machine loss.
