Detailed Description

template<int p = 5>
class mlpack::nmf::RandomAcolInitialization< p >

This class initializes the W matrix of the NMF algorithm by averaging p randomly chosen columns of V.

In this case, p is a template parameter. H is then set randomly.

Template Parameters:
Thenumber of random columns to average for each column of W.
