In fda.vi: Functional Data Analysis using Variational Inference

ELBO Convergence Check helper method

Description

Returns TRUE when the absolute ELBO change between consecutive iterations falls below convergence_threshold. Returns FALSE if either ELBO value is NULL or NA.

Usage

checkConvergence(elbo_c, elbo_prev, convergence_threshold)

Arguments

elbo_c	Numeric scalar. ELBO at the current iteration.
elbo_prev	Numeric scalar. ELBO at the previous iteration.
convergence_threshold	Positive scalar. Tolerance for convergence.

Value

Logical scalar.
