NMFact Properties |
The NMFact type exposes the following members.
| Name | Description | |
|---|---|---|
| ComputeCostAtEachStep | If true, the error of the approximation will be computed at each iteration step. If false, only the final error will be computed. | |
| Cost | Returns the error in the factorization in the last call to Factor. The error is computed using the Cost function in the INMFUpdateAlgorithm. | |
| DefaultCostAtEachStep | Whether, by default, the cost is evaluated at each step. | |
| DefaultNumIterations | Gets and sets the default number of iterations. | |
| DefaultUpdateAlgorithm | Gets and sets the default update algorithm. | |
| H | Returns the second factor in the factorization of V = WH. | |
| NumIterations | Gets and sets the number of iterations to perform. | |
| StepCost | A DoubleVector containing the error at each iteration step if ComputeCostAtEachStep is true. Otherwise it is a vector of length one containing only the final error. | |
| UpdateAlgorithm | Gets and sets the algorithm used by this factorization object. | |
| V | Returns the matrix being factored. | |
| W | Returns the first factor in the factorization of V = WH. |
