myICA | R Documentation |
The input data is assumed to be a matrix. When algorithms of MWCAParams and CoupledMWCAParams are specified as "myICA", This function is called in MWCA and CoupledMWCA.
myICA(Xn, k)
Xn |
The input matrix which has N-rows and M-columns. |
k |
The rank parameter (k <= min(N,M)) |
The output matrix which has N-rows and k-columns.
