Robust Multiple Description Neural Video Codec with Masked Transformer for Dynamic and Noisy Networks

no code implementations10 Dec 2024 Xinyue Hu, Wei Ye, Jiaxiang Tang, Eman Ramadan, Zhi-Li Zhang

We propose a novel MDC video codec, NeuralMDC, demonstrating how bidirectional transformers trained for masked token prediction can vastly simplify the design of MDC video codec.

MAC: A Benchmark for Multiple Attributes Compositional Zero-Shot Learning

no code implementations18 Jun 2024 Shuo Xu, Sai Wang, Xinyue Hu, Yutian Lin, Bo Du, Yu Wu

Compositional Zero-Shot Learning (CZSL) aims to learn semantic primitives (attributes and objects) from seen compositions and recognize unseen attribute-object compositions.

What Large Language Models Know and What People Think They Know

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

Here we explore the calibration gap, which refers to the difference between human confidence in LLM-generated answers and the models' actual confidence, and the discrimination gap, which reflects how well humans and models can distinguish between correct and incorrect answers.

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.
