Refined Pseudo labeling for Source-free Domain Adaptive Object Detection

no code implementations7 Mar 2023 Siqi Zhang, Lu Zhang, Zhiyong Liu

Domain adaptive object detection (DAOD) assumes that both labeled source data and unlabeled target data are available for training, but this assumption does not always hold in real-world scenarios.

A Dynamic 3D Spontaneous Micro-expression Database: Establishment and Evaluation

no code implementations31 Jul 2021 Fengping Wang, Jie Li, Siqi Zhang, Chun Qi, Yun Zhang, Danmin Miao

Micro-expressions are spontaneous, unconscious facial movements that show people's true inner emotions and have great potential in related fields of psychological testing.

The Complexity of Nonconvex-Strongly-Concave Minimax Optimization

no code implementations29 Mar 2021 Siqi Zhang, Junchi Yang, Cristóbal Guzmán, Negar Kiyavash, Niao He

In the averaged smooth finite-sum setting, our proposed algorithm improves over previous algorithms by providing a nearly-tight dependence on the condition number.

A Catalyst Framework for Minimax Optimization

no code implementations NeurIPS 2020 Junchi Yang, Siqi Zhang, Negar Kiyavash, Niao He

We introduce a generic \emph{two-loop} scheme for smooth minimax optimization with strongly-convex-concave objectives.
