)A Filebacked Big Matrix n x N. Data signals are stored in the matrix columns.
A Filebacked Big Matrix of the Nystrom kernel matrix \(s \times N\), where N is the number of signal in the training collection and s is the Nystrom sample size.
A Filebacked Big Matrix of cluster centroids.
A Filebacked Big matrix of the cluster assignment.
Maxumum number of neighbors.
Number of cores.
A directory to save the result, by default it is the working directory.
logical parameter that controls whether the resulting consensus chromatograms are stored as a Filebacked Big Matrix ('Centroid_preimage.bk'). Default is FALSE.
A matrix or a Filebacked Big Matrix if BIG = TRUE.
