class NMFactorization extends AnyRef

The NMFactorization class factors a matrix 'v' into two non negative matrices 'w' and 'h' such that 'v = wh' approximately.

Instance Constructors

  1. new NMFactorization(v: MatrixD, loops: Int = 10, r: Int = 0)

    v

    the matrix to be factored

    loops

    the number of iterations before checking the termination condition

    r

    factor the m-by-n matrix 'v' in to two factors: an m-by-r and r-by-n matrix

Value Members

  1. def factor(): (MatrixD, MatrixD)

    Factor the original matrix 'v' into left 'w' and right 'h' matrices by iteratively calling the 'update' method until the difference between 'v' and its approximation 'vv = w * h' is sufficiently small.

  2. var r: Int
