New algorithm ensures stable decision tree explanations after model updates

Researchers have introduced a new loss metric called Backward Compatibility Loss in Tree-based eXplanations (BCLTX) to address the issue of changing explanations in updated decision tree models. They also developed an algorithm, CART with Backward Compatibility in Tree-based eXplanations (CART-BCTX), which enhances the CART algorithm to minimize these explanation changes. Experiments on various datasets demonstrated that CART-BCTX offers a good balance between predictive performance and explanation stability, with computational costs similar to the standard CART algorithm.
