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…

FLUX: Geometry-Aware Longitudinal Flow Matching with Mixture of Experts

Josue Ortega Caro, Yongxu Zhang, Hannah M Batchelor +3

Many biological systems evolve through continuous local dynamics while switching between latent regimes defined by learning, stimulus context, internal state, or developmental stag…

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…

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…

Non-Markovian Discrete Diffusion with Causal Language Models

Yangtian Zhang, Sizhuang He, Daniel Levine +7

Discrete diffusion models offer a flexible, controllable approach to structured sequence generation, yet they still lag behind causal language models in expressive power. A key lim…

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…
