objective,NMFfit-method

optional target matrix used to compute the
  objective value.

an object computed using some algorithm, or
  that describes an algorithm itself.

object


  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.

objective,NMFfit-method function

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.

objective,NMFfit-method: Returns the objective function associated with the algorithm that computed the fitted NMF model `object`, or the objective value with respect to a given target matrix `y` if it is supplied.
