Data-Aware
Shapley Attributions
ShapBPT's core innovation is using data-aware Binary Partition Trees (BPTs) to structure feature coalitions. Unlike rigid, data-agnostic grids, BPTs dynamically align with intrinsic image morphology (e.g., coherent color and shape cues), enabling more semantically coherent explanations. This leads to significantly crisper saliency maps and reduces the computational budget required to identify relevant regions.

Crisp Saliency Map
Experiments across multiple computer vision tasks (classification, detection, attribute localization, and anomaly detection) and various datasets confirm ShapBPT's superior performance. It consistently achieves better structural alignment and efficiency compared to existing explainers such as SHAP's Partition Explainer (AA-b) and LIME (LIME-b).

Case Study: eXplainable Anomaly Detection (XAD)
In industrial inspection, reconstruction-based anomaly detection often produces noisy pixel-level error maps. ShapBPT transforms these raw outputs into actionable engineering evidence by localizing true defects and validating alarms. It helps distinguish real defects from reconstruction artifacts, supporting auditing "wrong-reason" alarms, and building trust in AI systems where reliable decision-making is paramount.
Impact: ShapBPT improves the precision of anomaly localization and helps interpret misclassifications, leading to more robust and explainable industrial AI deployments.
Enhanced Diagnostics
for Failure Analysis
ShapBPT in XAD provides critical diagnostic evidence. It reveals which image regions drive an anomaly score and whether it's due to a true defect or a reconstruction artifact. This is crucial for failure analysis, helping to interpret missed defects, false alarms, and expose cases where an alarm is triggered for the "wrong reasons" due to spurious cues like blurry borders or noise. This transparency enables engineers to refine models and build more trustworthy systems.
ShapBPT leverages the Owen recursion for hierarchical Shapley value approximations. This method efficiently distributes the total worth of a coalition among players, accounting for a persistent set of features (Q) as context. The key is the ability to adaptively refine regions based on estimated attribution mass, ensuring that computational budget is focused on semantically relevant image parts.
