The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

DPM++ learns an input-adaptive masked metric that dynamically selects reliable identity subspaces for each occluded instance, enabling matching to emphasize visibility-consistent evidence while suppressing unreliable components.

C2weakest assumption

That the CLIP-derived semantic priors transfer cleanly into the classifier-prototype space and that saliency-guided patch transfer produces occluded samples whose distribution matches real-world occlusion patterns closely enough to improve generalization.

C3one line summary

DPM++ learns input-adaptive masked metrics in a CLIP-supervised classifier-prototype space and uses saliency-guided patch transfer to synthesize realistic occluded training samples, outperforming prior methods on occluded and holistic re-ID benchmarks.
