solve_subproblem: Solve subproblems via coordinate descent, given the parameter...

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

Description

Solve the subproblem given which parameter set to update. For each subproblem, the exact solution is obtained

Usage

solve_subproblem(
  params.to.update = c("W", "lambda", "H"),
  X.list,
  W,
  H.list,
  b.list,
  lambda.list,
  verbose = T
)

Arguments

params.to.update	a characteristic scalar, choice of ('W','lambda','b','H'), specifying which set of parameters to update
X.list	a list of ncells-by-ngenes gene expression matrix
W	ngenes-by-r numeric matrix.
H.list	A list of factor loading matrix of size ncells-by-r
b.list	A list of shift vector of size p (ngenes).
lambda.list	A list of scaling vector of size p (ngenes).
verbose	boolean scalar, whether to show extensive program logs (default TRUE)

Value

a list containing updated parameters: W, H.list, lambda.list, b.list
