Researchers have developed MiSS, a novel framework for explaining the decisions of 3D point cloud classifiers. This black-box system uses perturbation-relative sufficiency reasoning to identify minimal sufficient coalitions of geometric regions that contribute to a classifier's prediction. MiSS separates candidate coalition proposal from verification, employing a weighted MaxSAT procedure for proposal and a statistical oracle for verification. Experiments on ModelNet40 and ShapeNet datasets with PointNet and PointMLP classifiers demonstrated that MiSS achieves higher precision and coverage compared to existing rule-based methods, while also reducing explanation time.
