EchoRL: Reinforcement Learning via Rollout Echoing

ICML 2026poster

Reinforcement Learning with Verifiable Rewards is an effective route for post-training to strengthen the reasoning capability of large language models. However, as training proceeds, the learning signal can collapse thus makes the training gain become marginal and ineffective. Specifically, a growin…

SiameseNorm: Breaking the Barrier to Reconciling Pre/Post-Norm

ICML 2026poster

Modern Transformers predominantly adopt the Pre-Norm paradigm for its optimization stability, foregoing the superior potential of the unstable Post-Norm architecture. Prior attempts to combine their strengths typically lead to a stability-performance trade-off. We attribute this phenomenon to a stru…
