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

Under explicit assumptions on noise features and cluster structure, relevant features are assigned consistently higher weights than noise features across a range of Minkowski exponents.

C2weakest assumption

The paper relies on explicit assumptions about the properties of noise features and the underlying cluster structure that allow the weight stability to separate signal from noise.

C3one line summary

Proposes FS-MWK++ and scalable SFS-MWK++ for unsupervised feature selection by aggregating stable feature weights from Minkowski weighted k-means++ across exponents, backed by theoretical analysis under noise and cluster assumptions.
