Opt3DGS: Optimizing 3D Gaussian Splatting with Adaptive Exploration and Curvature-Aware Exploitation

Ziyang Huang, Jiagang Chen, Jin Liu, Shunping Ji

AAAI 2026technical

3D Gaussian Splatting (3DGS) has emerged as a leading framework for novel view synthesis, yet its core optimization challenges remain underexplored. We identify two key issues in 3DGS optimization: entrapment in suboptimal local optima and insufficient convergence quality. To address these, we propo

Online Temporal Fusion for Vectorized Map Construction in Mapless Autonomous Driving

Jiagang Chen, Liangliang Pan, Shunping Ji, Ji Zhao, Zichao Zhang

RA-L 2025

To reduce the reliance on high-definition (HD) maps, a growing trend in autonomous driving is leveraging onboard sensors to generate vectorized maps online. However, current methods are mostly constrained by processing only single-frame inputs, which hampers their robustness and effectiveness in com
