⚠️There's a newer version (1.1.3) of this package.Take me there.

SAM (version 1.0.2)

Sparse Additive Machine

Description

The package SAM targets at high dimensional classification problem for complex data analysis. SAM is short for sparse additive machine, which is a explicit combination of high dimensional sparse additive modeling and support vector machine. Different from existing non-linear classification methods, which usually use, SAM adopts the computationally efficient basis spline technique. The optimization is solved by the Linearized Alternative Direction Method of Multipliers (L-ADMM). The computation is further accelerated by warm-start and active-set tricks. For users who are interested in large-scale problems, we also provide an implementation of L1 norm SVM for computational convenience.
