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

This paper provides an overview of recent developments in quickest change detection (QCD) for high-dimensional multi-sensor systems, with an emphasis on settings involving structural constraints and limited sensing resources.

C2weakest assumption

That the summarized classical QCD methodologies and their extensions to high-dimensional and constrained regimes accurately reflect the current state of the literature without significant omissions or misrepresentations.

C3one line summary

The paper surveys foundations and recent advances in multi-stream quickest change detection for high-dimensional systems with sparsity, sampling constraints, and heterogeneous signals.
