Effective pruning of task-trained recurrent neural networks using noisy fluctuations and connection rescaling

Aug 05, 2026

Existing pruning methods struggle to simultaneously preserve task performance and biological plausibility, particularly in functional recurrent neural networks. This work proposes and empirically validates noise-prune, a novel local pruning approach based on synaptic noise fluctuations: it retains critical connections through local sampling and rescales their weights to maintain average synaptic strength. The study demonstrates that both the connection sampling strategy and the weight rescaling mechanism are essential for performance, and revises the theoretically predicted optimal rescaling magnitude. Noise-prune significantly outperforms magnitude-only pruning strategies and matches or even exceeds the performance of non-local methods that rely on second-order information, while remaining computationally efficient and biologically plausible.

Adaptive Coopetition: Leveraging Coarse Verifier Signals for Resilient Multi-Agent LLM Reasoning

Oct 20, 2025

Existing reasoning-time strategies exhibit critical limitations: self-correction tends to reinforce initial biases, multi-agent collaboration (MAC) often suffers from insufficient coordination leading to collective errors, and high-accuracy verifiers require extensive human annotations. This paper proposes AdCo, the first framework to introduce a UCB-based adaptive “coopetition” mechanism—dynamically balancing cooperation and competition—into multi-agent LLM reasoning. AdCo leverages only coarse-grained verification signals to guide uncertainty-aware exploration and enhance trajectory diversity. Its methodology integrates multi-agent collaborative reasoning, iterative refinement, reasoning trajectory analysis, and knowledge diversity modeling. Evaluated on multiple mathematical reasoning benchmarks, AdCo achieves a 20% relative performance gain over state-of-the-art baselines while demonstrating robustness across varying sample sizes and configuration settings.
