Modulating task outcome value to mitigate real-world procrastination via noninvasive brain stimulation

no code implementations26 Jun 2025 Zhiyi Chen, Zhilin Ren, Wei Li, ZhenZhen Huo, ZhuangZheng Wang, Ye Liu, Bowen Hu, Wanting Chen, Ting Xu, Artemiy Leonov, Chenyan Zhang, Bernhard Hommel, Tingyong Feng

A leading model posits that procrastination arises from imbalanced competing motivations: the avoidance of negative task aversiveness and the pursuit of positive task outcomes, yet this theoretical framework has not fully validated in real-world settings and not applied effectively to guide interventions.

Deep Koopman-based Control of Quality Variation in Multistage Manufacturing Systems

no code implementations24 Jul 2024 Zhiyi Chen, Harshal Maske, Devesh Upadhyay, Huanyi Shui, Xun Huan, Jun Ni

This paper presents a modeling-control synthesis to address the quality control challenges in multistage manufacturing systems (MMSs).

Co-Speech Gesture Video Generation via Motion-Decoupled Diffusion Model

1 code implementation CVPR 2024 Xu He, Qiaochu Huang, Zhensong Zhang, Zhiwei Lin, Zhiyong Wu, Sicheng Yang, Minglei Li, Zhiyi Chen, Songcen Xu, Xiaofei Wu

While previous works mostly generate structural human skeletons, resulting in the omission of appearance information, we focus on the direct generation of audio-driven co-speech gesture videos in this work.

Principal Gradient Direction and Confidence Reservoir Sampling for Continual Learning

no code implementations21 Aug 2021 Zhiyi Chen, Tong Lin

In Principal Gradient Direction, we optimize a target gradient that not only represents the major contribution of past gradients, but also retains the new knowledge of the current gradient.

Revisiting Gradient Episodic Memory for Continual Learning

no code implementations25 Sep 2019 Zhiyi Chen, Tong Lin*

Gradient Episodic Memory (GEM) is an effective model for continual learning, where each gradient update for the current task is formulated as a quadratic program problem with inequality constraints that alleviate catastrophic forgetting of previous tasks.

Security Matters: A Survey on Adversarial Machine Learning

no code implementations16 Oct 2018 Guofu Li, Pengjia Zhu, Jin Li, Zhemin Yang, Ning Cao, Zhiyi Chen

Adversarial machine learning is a fast growing research area, which considers the scenarios when machine learning systems may face potential adversarial attackers, who intentionally synthesize input data to make a well-trained model to make mistake.
