objective,NMFfit-method

Returns the objective function associated with the
 algorithm that computed the fitted NMF model
 <code>object</code>, or the objective value with respect to a
 given target matrix <code>y</code> if it is supplied.

methods

Provides a framework to perform Non-negative Matrix
Factorization (NMF). The package implements a set of already published algorithms
and seeding methods, and provides a framework to test, develop and plug
new/custom algorithms. Most of the built-in algorithms have been optimized
in C++, and the main interface function provides an easy way of performing
parallel computations on multicore machines.
