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

Our approach automatically adapts class-specific margins based on label frequency, enforcing a higher penalty and tighter feature clustering for rare pathologies to counteract the effects of data imbalance. Extensive experiments ... demonstrate that our framework outperforms state-of-the-art methods.

C2weakest assumption

That a margin scaled solely by label frequency will produce tighter, more separable clusters for rare classes without introducing new overfitting to frequency statistics or harming performance on common classes.

C3one line summary

DMDSC adapts simplex-classifier margins dynamically according to label frequency to tighten clustering on rare medical classes and improve open-set rejection on imbalanced imaging datasets.
