HPS-Det: Dynamic Sample Assignment with Hyper-Parameter Search for Object Detection

Ji Liu, Dong Li, Zekun Li +4

Sample assignment plays a prominent part in modern object detection approaches. However, most existing methods rely on manual design to assign positive / negative samples, which do…

Dynamic Sparse R-CNN

Qinghang Hong, Fengming Liu, Dong Li +3

Sparse R-CNN is a recent strong object detection baseline by set prediction on sparse, learnable proposal boxes and proposal features. In this work, we propose to improve Sparse R-…

Compare learning: bi-attention network for few-shot learning

Li Ke, Meng Pan, Weigao Wen +1

Learning with few labeled data is a key challenge for visual recognition, as deep neural networks tend to overfit using a few samples only. One of the Few-shot learning methods cal…

Representing Videos as Discriminative Sub-graphs for Action Recognition

Dong Li, Zhaofan Qiu, Yingwei Pan +3

Human actions are typically of combinatorial structures or patterns, i.e., subjects, objects, plus spatio-temporal interactions in between. Discovering such structures is therefore…

Towards Discriminative Representation Learning for Unsupervised Person Re-identification

Takashi Isobe, Dong Li, Lu Tian +3

In this work, we address the problem of unsupervised domain adaptation for person re-ID where annotations are available for the source domain but not for target. Previous methods t…
