Initializes a new ("greedy") flash factor using irlba. This
can be somewhat faster than flash_greedy_init_default for large,
dense data matrices. For sparse matrices of class Matrix, the
default initialization should generally be preferred.
flash_greedy_init_irlba(flash, seed = 666, ...)A list of length two consisting of, respectively, the vector of initial values for loadings \(\ell_{\cdot k}\) and the vector of initial factor values \(f_{\cdot k}\).
A flash_fit object.
Since initialization is random, a default seed is set for reproducibility.
Additional parameters to be passed to irlba.
