Destination-Constrained Linear Dynamical System Modeling in Set-Valued Frameworks

no code implementations26 Mar 2024 Xiaowei Yang, Haiqi Liu, Fanqin Meng, Xiaojing Shen

Directional motion towards a specified destination is a common occurrence in physical processes and human societal activities.

Reliable Multimodality Eye Disease Screening via Mixture of Student's t Distributions

1 code implementation17 Mar 2023 Ke Zou, Tian Lin, Xuedong Yuan, Haoyu Chen, Xiaojing Shen, Meng Wang, Huazhu Fu

To address this issue, we introduce a novel multimodality evidential fusion pipeline for eye disease screening, EyeMoSt, which provides a measure of confidence for unimodality and elegantly integrates the multimodality information from a multi-distribution fusion perspective.

TBraTS: Trusted Brain Tumor Segmentation

4 code implementations19 Jun 2022 Ke Zou, Xuedong Yuan, Xiaojing Shen, Meng Wang, Huazhu Fu

In our method, uncertainty is modeled explicitly using subjective logic theory, which treats the predictions of backbone neural network as subjective opinions by parameterizing the class probabilities of the segmentation as a Dirichlet distribution.

An Unbiased Symmetric Matrix Estimator for Topology Inference under Partial Observability

no code implementations29 Mar 2022 Yupeng Chen, Zhiguo Wang, Xiaojing Shen

Network topology inference is a fundamental problem in many applications of network science, such as locating the source of fake news, brain connectivity networks detection, etc.

Towards Understanding the Impact of Model Size on Differential Private Classification

no code implementations27 Nov 2021 Yinchen Shen, Zhiguo Wang, Ruoyu Sun, Xiaojing Shen

Then we propose a feature selection method to reduce the size of the model, based on a new metric which trades off the classification accuracy and privacy preserving.
