New method offers exact contrastive explanations for gradient-boosted ensembles

A new research paper proposes a novel approach to explaining gradient-boosted ensembles by treating leaf values as coordinates. This perspective allows for exact contrastive explanations, where the difference between two instances is precisely mapped to specific splits within the ensemble's trees. The method has been applied to develop a recourse tool that reconstructs model decisions with high accuracy and demonstrates superior validity when recommendations are restricted to actionable changes.
