TEMPO: Makespan-Aware Expert-Parallel Load Balancing Across Memory- and Compute-Bound Regimes

Jie Li, Chenxin Jia, Jinliang Shen +5

In expert-parallel (EP) MoE serving, every layer synchronizes at the slowest GPU. Dispatchers balance token counts (EPLB, LPLB, UltraEP) or activated-expert counts (METRO), assumin…

JAGG: Jacobian-Aggregated Group Gradient for Efficient GRPO Training of Diffusion Models

Ruiyi Ding, Jie Li, He Kang +3

Group Relative Policy Optimization (GRPO) is a powerful reinforcement learning algorithm for aligning generative models with human preferences. While successful in large language m…

CFNN: Continued Fraction Neural Network

Chao Wang, Xuancheng Zhou, Ruilin Hou +2

Accurately characterizing non-linear functional manifolds with singularities is a fundamental challenge in scientific computing. While Multi-Layer Perceptrons (MLPs) dominate, thei…

PRPO: Aligning Process Reward with Outcome Reward in Policy Optimization

Ruiyi Ding, Yongxuan Lv, Xianhui Meng +4

Policy optimization for large language models often suffers from sparse reward signals in multi-step reasoning tasks. Critic-free methods like GRPO assign a single normalized outco…
