Preimage: Preimage

In chickn: 'Compressive' Hierarchical Kernel Clustering Toolbox

Description

Consensus chromatogram computation.

Usage

Preimage(
  Data,
  K_W1,
  C_out,
  Cl_assign,
  max_Nsize = 32,
  ncores = 4,
  DIR_out = getwd(),
  BIG = FALSE
)

Arguments

Data	A Filebacked Big Matrix n x N. Data signals are stored in the matrix columns.
K_W1	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.
C_out	A Filebacked Big Matrix of cluster centroids.
Cl_assign	A Filebacked Big matrix of the cluster assignment.
max_Nsize	Maxumum number of neighbors.
ncores	Number of cores.
DIR_out	A directory to save the result, by default it is the working directory.
BIG	logical parameter that controls whether the resulting consensus chromatograms are stored as a Filebacked Big Matrix ('Centroid_preimage.bk'). Default is FALSE.

Value

A matrix or a Filebacked Big Matrix if BIG = TRUE.
