Detailed Description
template<int p = 5>class mlpack::amf::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:
The number of random columns to average for each column of W.
