NMFNonsmooth |
The NMFNonsmoothUpdate type exposes the following members.
| Name | Description | |
|---|---|---|
| SmoothingMatrix |
Gets the smoothing matrix.
The smoothing matrix is a positive
symmetric matrix S defined as:
S = (1 - theta)I + (theta/q)11'
where I is the identity matrix, 1 is a vector of ones and the parameter t
is between 0 and 1, inclusive. See class description.

| Theta |
The Nonsmooth Nonnegative Matrix Factorization is defined as
V = WSHwhere V, W, and H are the same as in the original NMF model. The positive symmetric matrix S is a "smoothing" matrix defined as:
S = (1 - theta)I + (theta/q)11'
