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

Extensive experiments on diverse multimodal benchmarks demonstrate that the proposed framework consistently outperforms existing pruning methods across a wide range of sparsity ratios.

C2weakest assumption

That representing layer-wise hidden states as point clouds and quantifying their evolution with simplicial complexes and zigzag persistent homology accurately captures global and dynamic representational transitions better than local similarity metrics or static proxies.

C3one line summary

A topology-aware pruning framework models layer representation evolution in LVLMs via simplicial complexes and zigzag persistent homology to enable adaptive removal of layers while outperforming existing methods on multimodal benchmarks.
