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

CAWI consistently delivers significant improvements in predictive performance over conventional random initialization across 83 diverse classification benchmarks and two biomedical datasets using standard shallow and deep RdNN architectures.

C2weakest assumption

That sampling the input-to-hidden weights from a fitted copula will improve the conditioning and predictive performance of the closed-form output-layer solution without introducing new instabilities or requiring changes to the solver.

C3one line summary

CAWI replaces standard random initialization of input-to-hidden weights in randomized neural networks with samples drawn from a data-fitted copula that preserves observed feature dependencies, yielding consistent accuracy gains on 83 classification benchmarks.
