Semi-Supervised Domain Generalization in Real World:New Benchmark and Strong Baseline

no code implementations19 Nov 2021 Luojun Lin, Han Xie, Zhifeng Yang, Zhishu Sun, Wenxi Liu, Yuanlong Yu, WeiJie Chen, Shicai Yang, Di Xie

In this paper, we introduce a novel task, termed as semi-supervised domain generalization, to study how to interact the labeled and unlabeled domains, and establish two benchmarks including a web-crawled dataset, which poses a novel yet realistic challenge to push the limits of existing technologies.

A Homotopy Coordinate Descent Optimization Method for $l_0$-Norm Regularized Least Square Problem

no code implementations13 Nov 2020 Zhenzhen Sun, Yuanlong Yu

This paper proposes a homotopy coordinate descent (HCD) method to solve the $l_0$-norm regularized least square ($l_0$-LS) problem for compressed sensing, which combine the homotopy technique with a variant of coordinate descent method.

Joint Adaptive Graph and Structured Sparsity Regularization for Unsupervised Feature Selection

1 code implementation9 Oct 2020 Zhenzhen Sun, Yuanlong Yu

After optimized, a subset of optimal features will be selected in group, and the number of selected features will be determined automatically.

Robust Multi-class Feature Selection via $l_{2,0}$-Norm Regularization Minimization

no code implementations8 Oct 2020 Zhenzhen Sun, Yuanlong Yu

Feature selection is an important data pre-processing in data mining and machine learning, which can reduce feature size without deteriorating model's performance.

Visualizing the Invisible: Occluded Vehicle Segmentation and Recovery

no code implementations ICCV 2019 Xiaosheng Yan, Yuanlong Yu, Feigege Wang, Wenxi Liu, Shengfeng He, Jia Pan

We conduct comparison experiments on this dataset and demonstrate that our model outperforms the state-of-the-art in tasks of recovering segmentation mask and appearance for occluded vehicles.

Deformable Object Tracking with Gated Fusion

no code implementations27 Sep 2018 Wenxi Liu, Yibing Song, Dengsheng Chen, Shengfeng He, Yuanlong Yu, Tao Yan, Gerhard P. Hancke, Rynson W. H. Lau

In addition, we also propose a gated fusion scheme to control how the variations captured by the deformable convolution affect the original appearance.
