flash_greedy_init_irlba {flashier} | R Documentation |
Initialize a flash factor using IRLBA
Description
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.
Usage
flash_greedy_init_irlba(flash, seed = 666, ...)
Arguments
flash |
A |
seed |
Since initialization is random, a default seed is set for reproducibility. |

Additional parameters to be passed to |
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}
.
