initialization {M2SMF}

initialize the sub-matrix Ci into alpha*Li by SVD

Description

Li takes the first k columns of matrix d in SVD, while alpha is the mean of all the u of SVD result in each modality

Usage

initialization(WL, k)

Arguments

WL

A list of similarity matrices

k

A parameter to specify the cluster number

Value

A list with N+2 elements, the former N as modality private sub-matrices, the Nth as the shared sub-matrix and the last one as 1
