LEAP: Lean Environment-Feedback via Adaptive Pruning for Code RL in GPU Kernel Generation

Tankun Li, Zhi Chen, Yaohua Tang

Post-training large language models (LLMs) via reinforcement learning (RL) has significantly advanced code generation capabilities. To bypass the heavy memory footprint of critic n…

Beyond the Best Teacher: Expanding and Compressing the Reasoning Solution Manifold

Songshuo Lu, Zhi Chen, Yaohua Tang

The paper proposes an expand‑then‑compress framework that builds a diverse set of RL‑trained teacher models and then distills them into a single student model, improving reasoning,…

MusaCoder: Native GPU Kernel Generation with Full-Stack Training on Moore Threads GPU

Kun Cheng, Songshuo Lu, Sicong Liao +7

Native GPU kernel generation turns high-level tensor programs into executable, efficient low-level code. Existing Large Language Models (LLMs) struggle with this task, while execut…

ReorgGS: Equivalent Distribution Reorganization for 3D Gaussian Splatting

Luchao Wang, Kaimin Liao, Qian Ren +3

A converged 3D Gaussian Splatting (3DGS) model may approximate the target scene while remaining poorly parameterized for further optimization. We identify this failure mode as \emp…
