wsrf: Weighted Subspace Random Forest

The wsrf package is a parallel implementation of the Weighted Subspace Random Forest algorithm proposed (wsrf). A novel variable weighting method is used for variable subspace selection in place of the traditional approach of random variable sampling. This new approach is particularly useful in building models for high dimensional data—often consisting of thousands of variables. Parallel computation is used to take advantage of multi-core machines and clusters of machines to build random forest models from high dimensional data with reduced elapsed times.
