Residual Visual Credit Optimization: Conserved Evidence Routing for Multimodal Reinforcement Learning

Lin Qiu, Yao Liu, Diyi Hu وآخرون · 2026

Reinforcement learning with verifiable rewards scales multimodal reasoning, but an outcome reward says how much a trajectory is worth, not how that value should be spread over the decisions that produced it. We introduce Residual Visual Credit Optimization (RVCO), which treats token credit as a conserved routing proble …

The Evolution of Attention in Large Language Models: Mechanisms, Trade-offs, and Emerging Trends

Zhentao Tan, Jingyi Shen, Yanbo Li وآخرون · 2026

Self-attention gives LLMs fine-grained, query-dependent access to context, but dense token interactions incur quadratic prefill cost and a key--value cache growing with context length. Research thus spans explicit-memory compression, sparse access, recurrent state construction, structured state dynamics, and heterogene …
