MoRSE: Task-Oriented Multi-Agent System with Mixture of Role-Subtask Experts

Peiwen Li, Shiyang Zhang, Yangtian Zhang +3

Large language model-based multi-agent systems have recently shown strong potential for complex, long-horizon tasks. However, existing methods mainly rely on coarse prompt-level di…

STRIDE: Post-Training LLMs to Reason and Refine Bio-Sequences via Edit Trajectories

Daiheng Zhang, Shiyang Zhang, Sizhuang He +3

Discrete biological sequence optimization often requires goal-directed, parser-valid edits to an existing protein or molecule. Diffusion models support iterative refinement but do…

Learning Permutation Distributions via Reflected Diffusion on Ranks

Sizhuang He, Yangtian Zhang, Shiyang Zhang +1

The finite symmetric group S_n provides a natural domain for permutations, yet learning probability distributions on S_n is challenging due to its factorially growing size and disc…

Echo-N1: Affective RL Frontier

Naifan Zhang, Ruihan Sun, Ruixi Su +9

The LLM field has spent a year perfecting RL for tasks machines already excel at, math, code, and deterministic reasoning, while completely sidestepping the domain that actually de…

TANTE: Time-Adaptive Operator Learning via Neural Taylor Expansion

Zhikai Wu, Sifan Wang, Shiyang Zhang +5

Operator learning for time-dependent partial differential equations (PDEs) has seen rapid progress in recent years, enabling efficient approximation of complex spatiotemporal dynam…

Intelligence at the Edge of Chaos

Shiyang Zhang, Aakash Patel, Syed A Rizvi +5

We explore the emergence of intelligent behavior in artificial systems by investigating how the complexity of rule-based systems influences the capabilities of models trained to pr…
