Maximum number of iterations without improvement in cross-validation
Alias: none
Argument(s): INTEGER
Default: 0
The purpose of this control is to cease auto-refinement when improvement in the cross-validation score appears to have stalled or occurs too slowly.
A rolling average of improvement in the cross-validation score is computed over soft_convergence_limit
iterations. Auto-refinement is halted if the average becomes smaller than the convergence_tolerance
. The average is computed but ignored until the number of iterations has exceeded soft_convergence_limit
.
The default setting of 0 disables soft convergence.
