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

Experimental results demonstrate that our method achieves marginally superior performance compared to existing leading techniques in closed-world settings and significantly improves over existing baselines in open-world scenarios.

C2weakest assumption

That the 1D Deformable architecture combined with feature disentanglement, one-to-many matching, and diversity loss can effectively handle overlapping and ambiguous events while enabling incremental learning of novel sounds.

C3one line summary

Introduces OW-SED paradigm and WOOT transformer framework to detect known sounds, identify unseen events, and incrementally learn in open audio environments.
