Detailed Description

Sparse Distribution.

(2n+m)-dimensional distribution with sparse binary values. Every example from this distribution consists of a vector with k ones and 2n+m-k zeros. The first one is within the first n coordinates for positive and in the second n variables for negative class examples. The remaining ones are drawn independently among the remaining variables.
