infer_intensities {vrnmf}

Infer a matrix of non-negative intensities in NMF

Description

infer_intensities estimates a non-negative matrix D that optimizes the objective function F = ||X - C*D||^2 using per-row quadratic programming.

Usage

infer_intensities(C, X, esign = "pos", n.cores = 1)

Arguments

C

Numeric matrices.

X

Numeric matrices.

esign

A character. Keep elements of matrix D non-negative ("pos") or not ("all). (default="pos")

n.cores

An integer. Number of cores to use. (default=1)

Value

Fitted matrix D.
