StopReason

class StopReason

Bases: str, Enum

Reason why early stopping was triggered.

Inherits from str so that values serialize naturally to JSON and can be compared directly with plain strings.

Attributes Summary

COST_VARIANCE_SETTLED	Variance of recent cost values dropped below variance_threshold.
GRADIENT_BELOW_THRESHOLD	L2 norm of the gradient fell below grad_norm_threshold.
PATIENCE_EXCEEDED	Cost did not improve by at least min_delta for patience consecutive iterations.
