Tractography with T1-weighted MRI and associated anatomical constraints on clinical quality diffusion MRI

no code implementations27 Mar 2024 Tian Yu, Yunhe Li, Michael E. Kim, Chenyu Gao, Qi Yang, Leon Y. Cai, Susane M. Resnick, Lori L. Beason-Held, Daniel C. Moyer, Kurt G. Schilling, Bennett A. Landman

Diffusion MRI (dMRI) streamline tractography, the gold standard for in vivo estimation of brain white matter (WM) pathways, has long been considered indicative of macroscopic relationships with WM microstructure.

Truth-Aware Context Selection: Mitigating the Hallucinations of Large Language Models Being Misled by Untruthful Contexts

1 code implementation12 Mar 2024 Tian Yu, Shaolei Zhang, Yang Feng

Although large language models (LLMs) have demonstrated impressive text generation capabilities, they are easily misled by the untruthful context provided by users or knowledge augmentation tools, thereby producing hallucinations.

Edge Deep Learning Enabled Freezing of Gait Detection in Parkinson's Patients

no code implementations27 Nov 2022 Ourong Lin, Tian Yu, Yuhan Hou, Yi Zhu, Xilin Liu

In a validation using a public dataset, the prototype developed achieved a FoG detection sensitivity of 88. 8% and an F1 score of 85. 34%, using less than 20 k trainable parameters per sensor node.

Reinforcement Learning Based User-Guided Motion Planning for Human-Robot Collaboration

no code implementations1 Jul 2022 Tian Yu, Qing Chang

Therefore, it is highly desirable to have a flexible motion planning method, with which robots can adapt to specific task changes in unstructured environments, such as production systems or warehouses, with little or no intervention from non-expert personnel.

Wetting equilibrium in a rectangular channel

no code implementations3 Dec 2020 Tian Yu, Qicheng Sun, Chen Zhao, Jiajia Zhou, Masao Doi

When a capillary channel with corners is wetted by a fluid, there are regions where the fluid fills the whole cross-section and regions where only the corners are filled by the fluid.
