How Nonnegative Matrix Factorization Demonstrator works

Approximate a nonnegative matrix with lower-rank nonnegative factors using multiplicative updates. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1

Factorization
The resulting factorization returned as an object.

Limitations and assumptions

  • Dimension compatibility, numeric conditioning, symmetry, positive definiteness, rank, scaling, tolerance, and floating-point precision affect matrix results. Serialization formats may lose types or precision.
  • Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Alternative or Complementary approaches

Check dimensions and prerequisites, compute reconstruction or residual error for decompositions, and compare ill-conditioned cases with a trusted numerical library.
