Multi-Resolution Attribution from Adaptive Routing State

Read the original on arXiv AI →

The paper demonstrates that the routing state accumulated by adaptive hierarchical systems inherently provides a coherent attribution across the hierarchy. A leaf node’s contribution is the product of local routing weights along its path, while an internal node receives the corresponding prefix product, ensuring that finer readouts sum exactly to coarser ones. This attribution reflects the router’s learned preferences rather than intrinsic component values, and is shown to reveal meaningful structure at multiple levels in LLM, Census, agentic, and telecom-network hierarchies, with higher‑level readouts often offering clearer organization than leaf‑level ones.

Self-evolving network verifiers

arXiv:2608. 11340v1 Announce Type: cross Abstract: Symbolic network verifiers can reason about correctness across vast spaces of routing inputs and failures, but only for the protocols and features an expert has encoded by hand.

Beyond the Trace: Coupling an Interpretable Reasoning-State Readout to Native MoE Routing

The paper introduces a two‑level readout for mixture‑of‑experts reasoning models. First, it compresses the model’s internal reasoning states into a 64‑dimensional semantic frame (J64) that reveals process dynamics beyond the emitted trace. Second, it reconstructs this frame from native expert‑routing statistics (R64), achieving high correlation and preserving most predictive gains while enabling low‑overhead, test‑time decision making.
