In pengminshi/cFIT: cFIT (common Factor Space Integration & Transfer)

Description

argmin_{W>=0} ||X- HW^T diag(lambd) - 1_n b^T||_F^2 += \frac{1}{2μ_t}\|W-W^{t-1}\|_F/

Usage

solve_W_penalized(X.list, H.list, lambda.list, b.list, W.old, iter)

Arguments

X.list	A list of ncells-by-ngenes gene expression matrix.
H.list	A list of factor loading matrix of size ncells-by-r
lambda.list	A list of scaling vector of size p (ngenes).
b.list	A list of shift vector of size p (ngenes).
W.old	W from last iteration.
iter	current iteration, for calculating the step size.

Value

W ngenes-by-r common factor matrix shared among datasets
