Detailed Description

template<class InputType>
class shark::DataDistribution< InputType >

A DataDistribution defines an unsupervised learning problem.

The unsupervised learning problem is defined by an explicit distribution (in contrast to a finite dataset). The only method we need is to draw a sample from the distribution.
