Learning a Terrain- and Robot-Aware Dynamics Model for Autonomous Mobile Robot Navigation

no code implementations17 Sep 2024 Jan Achterhold, Suresh Guttikonda, Jens U. Kreber, Haolong Li, Joerg Stueckler

In this article, we propose a novel approach for learning a probabilistic, terrain- and robot-aware forward dynamics model (TRADYN) which can adapt to such variations and demonstrate its use for navigation.

Exploring Mathematical Extrapolation of Large Language Models with Synthetic Data

no code implementations4 Jun 2024 Haolong Li, Yu Ma, Yinqi Zhang, Chen Ye, Jie Chen

In this paper, through a newly proposed arithmetical puzzle problem, we show that the model can perform well on multi-step reasoning tasks via fine-tuning on high-quality synthetic data.

Formation of edge pressure pedestal and reversed magnetic shear due to toroidal rotation in a tokamak equilibrium

no code implementations14 Jan 2021 Haolong Li, Ping Zhu

Here the formation of pressure pedestal along with the reversed magnetic shear region is shown to be the natural outcome of the MHD tokamak equilibrium in a self-consistent response to the presence of a localized toroidal rotation typically observed in H-mode or QH-mode.
