NMFDivergence |
The NMFDivergenceUpdate type exposes the following members.
Name | Description | |
---|---|---|
NMFDivergenceUpdate | Constructs a NMFDivergenceUpdate instance. |
Name | Description | |
---|---|---|
Clone | Returns a deep copy of self. | |
Cost | Returns the value of the cost function for the non-negative factorization of V = WH. The cost function is minimized by the factorization. | |
InitialFactors | Provides the initial factors for the iteration process that computes W and H in the non-negative matrix factorization V = WH. | |
IterationStep | Updates the factors W and H in the non-negative matrix factorization V = WH. |
D = sum(i,j)Vij*log(Vij/(WH)ij) - Vij + (WH)ijSee the paper Metagenes and Molecular Pattern Discovery Using Matrix Factorization Jean-Philippe Brunet, Pablo Tamayo, Todd R. Golub, and Jill P. Mesirov.
