Detailed Description

Dimensionality reduction strategies for variable selection.

Contains the abstract DRStrategy interface and concrete implementations that select a subset of variables before projection pursuit optimisation. DRNoopStrategy uses all variables (single trees); DRUniformStrategy samples uniformly at random (forests).

New strategies must implement the pure virtual methods including to_json() for serialization support.
