Tactic: Adaptive Sparse Attention with Clustering and Distribution Fitting for Long-Context LLMs

ICLR 2026poster

Long-context models are essential for many applications but face inefficiencies in loading large KV caches during decoding. Prior methods enforce fixed token budgets for sparse attention, assuming a set number of tokens can approximate full attention. However, these methods overlook variations in th…

High-order Interactions Modeling for Interpretable Multi-Agent Q-Learning

NeurIPS 2025poster

The ability to model interactions among agents is crucial for effective coordination and understanding their cooperation mechanisms in multi-agent reinforcement learning (MARL). However, previous efforts to model high-order interactions have been primarily hindered by the combinatorial explosion or…
