NOCT: Nonlinear Observability with Constraints and Time Offset

no code implementations16 Jul 2022 Jianzhu Huai, Yukai Lin, Yujia Zhang

To this end, we propose procedures to convert a system model of affine control inputs with linear constraints into a constraint-free standard model which is apt to be analyzed by the classic observability analysis procedure.

ChildPredictor: A Child Face Prediction Framework with Disentangled Learning

1 code implementation21 Apr 2022 Yuzhi Zhao, Lai-Man Po, Xuehui Wang, Qiong Yan, Wei Shen, Yujia Zhang, Wei Liu, Chun-Kit Wong, Chiu-Sing Pang, Weifeng Ou, Wing-Yin Yu, Buhua Liu

On this basis, we formulate predictions as a mapping from parents' genetic factors to children's genetic factors, and disentangle them from external and variety factors.

Demographic Confounding Causes Extreme Instances of Lifestyle Politics on Facebook

no code implementations17 Jan 2022 Alexander Ruch, Yujia Zhang, Michael Macy

We validate our measures of political alignment and lifestyle politics using the General Social Survey and find similar demographic entanglements with lifestyle politics existed before social media such as Facebook were ubiquitous, giving us strong confidence that our results are not due to echo chambers or filter bubbles.

RepBin: Constraint-based Graph Representation Learning for Metagenomic Binning

1 code implementation22 Dec 2021 Hansheng Xue, Vijini Mallawaarachchi, Yujia Zhang, Vaibhav Rajan, Yu Lin

We solve the binning problem by developing new algorithms for (i) graph representation learning that preserves both homophily relations and heterophily constraints (ii) constraint-based graph clustering method that addresses the problems of skewed cluster size distribution.

TB-Net: A Three-Stream Boundary-Aware Network for Fine-Grained Pavement Disease Segmentation

1 code implementation7 Nov 2020 Yujia Zhang, Qianzhong Li, Xiaoguang Zhao, Min Tan

It consists of three streams fusing the low-level spatial and the high-level contextual representations as well as the detailed boundary information.

A Generalized Zero-Shot Framework for Emotion Recognition from Body Gestures

no code implementations13 Oct 2020 Jinting Wu, Yujia Zhang, Xiaoguang Zhao, Wenbin Gao

In order to solve this problem, we introduce a Generalized Zero-Shot Learning (GZSL) framework, which consists of three branches to infer the emotional state of the new body gestures with only their semantic descriptions.
