IDP-PGFE: An Interpretable Disruption Predictor based on Physics-Guided Feature Extraction

no code implementations28 Aug 2022 Chengshuo Shen, Wei Zheng, Yonghua Ding, Xinkun Ai, Fengming Xue, Yu Zhong, Nengchao Wang, Li Gao, Zhipeng Chen, Zhoujun Yang, Zhongyong Chen, Yuan Pan, J-TEXT team

Understanding why a predictor makes a certain prediction can be as crucial as the prediction's accuracy for future tokamak disruption predictors.

DACSR: Decoupled-Aggregated End-to-End Calibrated Sequential Recommendation

no code implementations22 Apr 2022 Jiayi Chen, Wen Wu, Liye Shi, Yu Ji, Wenxin Hu, Wei Zheng, Liang He

In this work, we focus on the calibrated recommendations for sequential recommendation, which is connected to both fairness and diversity.

Long-Tail Session-based Recommendation from Calibration

no code implementations5 Dec 2021 Jiayi Chen, Wen Wu, Wei Zheng, Liang He

Accurate predictions in session-based recommendations have progressed, but a few studies have focused on skewed recommendation lists caused by popularity bias.

The Stackelberg Equilibrium for One-sided Zero-sum Partially Observable Stochastic Games

no code implementations17 Sep 2021 Wei Zheng, Taeho Jung, Hai Lin

We propose a space partition approach to solve the game iteratively and show that the value function of the leader is piece-wise linear and the value function of the follower is piece-wise constant for multiple stages.

Subject-independent Human Pose Image Construction with Commodity Wi-Fi

no code implementations22 Dec 2020 Shuang Zhou, Lingchao Guo, Zhaoming Lu, Xiangming Wen, Wei Zheng, Yiming Wang

Existing papers achieve good results when constructing the images of subjects who are in the prior training samples.

A Multi-View Dynamic Fusion Framework: How to Improve the Multimodal Brain Tumor Segmentation from Multi-Views?

no code implementations21 Dec 2020 Yi Ding, Wei Zheng, Guozheng Wu, Ji Geng, Mingsheng Cao, Zhiguang Qin

Moreover, the multi-view fusion loss, which consists of the segmentation loss, the transition loss and the decision loss, is proposed to facilitate the training process of multi-view learning networks so as to keep the consistency of appearance and space, not only in the process of fusing segmentation results, but also in the process of training the learning network.

Graph Neural Network Encoding for Community Detection in Attribute Networks

no code implementations6 Jun 2020 Jianyong Sun, Wei Zheng, Qingfu Zhang, Zongben Xu

Based on the new encoding method and the two objectives, a multiobjective evolutionary algorithm (MOEA) based upon NSGA-II, termed as continuous encoding MOEA, is developed for the transformed community detection problem with continuous decision variables.

Ball: An R package for detecting distribution difference and association in metric spaces

2 code implementations9 Nov 2018 Jin Zhu, Wenliang Pan, Wei Zheng, Xueqin Wang

The rapid development of modern technology facilitates the appearance of numerous unprecedented complex data which do not satisfy the axioms of Euclidean geometry, while most of the statistical hypothesis tests are available in Euclidean or Hilbert spaces.


Regression trees for longitudinal and multiresponse data

no code implementations21 Sep 2012 Wei-Yin Loh, Wei Zheng

Previous algorithms for constructing regression tree models for longitudinal and multiresponse data have mostly followed the CART approach.
