flash_verbose_elbo_diff {flashier}

Display the difference in ELBO

Description

Displays the difference in the variational lower bound (ELBO) from one iteration to the next.

Usage

flash_verbose_elbo_diff(curr, prev, k)

Arguments

curr

The flash_fit object from the current iteration.

prev

The flash_fit object from the previous iteration.

k

Only used during sequential backfits (that is, calls to flash_backfit where extrapolate = FALSE). It then takes the index of the factor/loadings pair currently being optimized.

Details

This function is an example of a function that may be passed to parameter fns in function flash_set_verbose to customize the output that is printed after each greedy or backfitting iteration. See flash_set_verbose for details and examples.

Value

A character string, suitable for printing progress updates.
