EvoMAS: Heuristics in the Loop—Evolving Smarter Agentic Workflows

ICML 2026poster

The rapid development of Large Language Models has driven Multi-Agent Systems (MAS) growth, but constructing efficient MAS still requires labor-intensive manual design. Current automation methods often generate templated agents, rely on monolithic optimization, and ignore task complexity gradients. …

MedAtlas: Evaluating LLMs for Multi-Round, Multi-Task Medical Reasoning Across Diverse Imaging Modalities and Clinical Text

AAAI 2026technical

Artificial intelligence has demonstrated significant potential in clinical decision-making; however, developing models capable of adapting to diverse real-world scenarios and performing complex diagnostic reasoning remains a major challenge. Existing medical multi-modal benchmarks are typically limi

Mixture-of-Trees: Learning to Select and Weigh Reasoning Paths for Efficient LLM Inference

AAAI 2026technical

We introduce Mixture-of-Trees (MoT), a novel framework that integrates sparse expert activation with structured tree-based reasoning for efficient LLM inference. MoT employs a learned gating mechanism to selectively activate only the most relevant expert reasoning trees for each problem, where exper

Topological Active Inference for Task Disambiguation

ICML 2026poster

In open-ended domains, natural language instructions are often *underspecified*, mapping to multiple valid yet functionally distinct latent intents. While Large Language Models (LLMs) excel at generation, their ability to resolve such *task ambiguity* through interaction is currently hampered by *se…

MECoT: Markov Emotional Chain-of-Thought for Personality-Consistent Role-Playing

ACL 2025finding

Large Language Models (LLMs) have shown remarkable capabilities in role-playing dialogues, yet they often struggle to maintain emotionally consistent and psychologically plausible character personalities. We present MECoT (Markov Emotional Chain-of-Thought), a framework that enhances LLMs’ ability t…
