The Calibration Gap between Model and Human Confidence in Large Language Models

no code implementations24 Jan 2024 Mark Steyvers, Heliodoro Tejeda, Aakriti Kumar, Catarina Belem, Sheer Karny, Xinyue Hu, Lukas Mayer, Padhraic Smyth

Recent work has focused on the quality of internal LLM confidence assessments, but the question remains of how well LLMs can communicate this internal model confidence to human users.

Volumetric Medical Image Segmentation via Scribble Annotations and Shape Priors

no code implementations12 Oct 2023 Qiuhui Chen, Haiying Lyu, Xinyue Hu, Yong Lu, Yi Hong

In this paper, we propose a scribble-based volumetric image segmentation, Scribble2D5, which tackles 3D anisotropic image segmentation and aims to its improve boundary prediction.

Memory Efficient Temporal & Visual Graph Model for Unsupervised Video Domain Adaptation

no code implementations13 Aug 2022 Xinyue Hu, Lin Gu, Liangchen Liu, Ruijiang Li, Chang Su, Tatsuya Harada, Yingying Zhu

Existing video domain adaption (DA) methods need to store all temporal combinations of video frames or pair the source and target videos, which are memory cost expensive and can't scale up to long videos.

Mining On Alzheimer's Diseases Related Knowledge Graph to Identity Potential AD-related Semantic Triples for Drug Repurposing

no code implementations17 Feb 2022 Yi Nian, Xinyue Hu, Rui Zhang, Jingna Feng, Jingcheng Du, Fang Li, Yong Chen, Cui Tao

The 1, 672, 110 filtered triples were used to train with knowledge graph completion algorithms (i. e., TransE, DistMult, and ComplEx) to predict candidates that might be helpful for AD treatment or prevention.

Physics-Guided Deep Neural Networks for Power Flow Analysis

no code implementations31 Jan 2020 Xinyue Hu, Haoji Hu, Saurabh Verma, Zhi-Li Zhang

Nevertheless, prior data-driven approaches suffer from poor performance and generalizability, due to overly simplified assumptions of the PF problem or ignorance of physical laws governing power systems.
