| flash_greedy_init_softImpute {flashier} | R Documentation |
Initialize a flash factor using softImpute
Description
Initializes a new ("greedy") flash factor using softImpute.
When there is missing data, this can yield better results than
flash_greedy_init_default without sacrificing much (if any) speed.
Usage
flash_greedy_init_softImpute(flash, seed = 666, ...)
Arguments
flash |

seed |
Since initialization is random, a default seed is set for reproducibility. |

Value
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}.
