EpiAgent: Epistemic Self-Play for LLM Agents

The proposed EpiAgent is a framework that equips LLM-based agents with an explicit, learnable epistemic layer, which maintains beliefs over others' private information and combines these beliefs with the agent's available information into an epistemic state for action selection.

Information-Time Proximal Policy Optimization

This paper proposes InfoPPO, which reparameterizes temporal progression using information density rather than raw token count, and extends performance-difference and policy-improvement analyses to the information-time MDP, deriving a policy-improvement lower bound when policy changes are regulated by information densit...

Embracing Flow Unsteadiness: A High-Throughput Learning Platform Enables Vortex-Exploiting Bioinspired Propulsion

Biological swimmers and flyers exploit unsteady vortices for propulsion, whereas engineered vehicles usually suppress them as disturbances. Learning such flow exploitation in machines is difficult because real-fluid interaction data are scarce and unstructured exploration is unstable in high-dimensional, history-depend...

Remember and Reweight: Enhancing Multi-Agent Debate with Experience Memory and Confidence Estimation

This work proposes R$^2$-MAD (Remember and Reweight for Multi-Agent Debate), a framework that equips agents with an experience memory accumulated from past debates that achieves consistent improvements over existing single-agent and MAD baselines.

UniMem: Complementary Episodic-to-Parametric Memory for Boundary-Agnostic Task Streams

Inspired by the human brain, which balances plasticity and stability through complementary episodic storage and gradual consolidation, UniMem is proposed, a self-routing framework for autonomous memory management that consistently outperforms baselines while maintaining execution fidelity.
