arXiv:2510. 07884v2 Announce Type: replace-cross Abstract: Weak-to-strong generalization provides a promising paradigm for scaling large language models (LLMs) by training stronger models on samples from aligned weaker ones, without requiring human feedback or explicit reward modeling.

Attention-Guided Reliability Scaling for Contrastive Decoding in Robust Audio-Visual Speech Recognition

The paper introduces a method to improve audio‑visual speech recognition by applying contrastive decoding (CD) that contrasts audio‑only with audio‑visual conditioning within the same model. It addresses the issue of a fixed CD strength by scaling the influence adaptively for each token, using reliability signals from attention dynamics and predictive divergence. Experiments on the LRS3 dataset demonstrate consistent gains in both clean and low‑SNR scenarios.
