PseCo: Pseudo Labeling and Consistency Training for Semi-Supervised Object Detection

no code implementations30 Mar 2022 Gang Li, Xiang Li, Yujie Wang, Shanshan Zhang, Yichao Wu, Ding Liang

Specifically, for pseudo labeling, existing works only focus on the classification score yet fail to guarantee the localization precision of pseudo boxes; For consistency training, the widely adopted random-resize training only considers the label-level consistency but misses the feature-level one, which also plays an important role in ensuring the scale invariance.

Global Context with Discrete Diffusion in Vector Quantised Modelling for Image Generation

no code implementations3 Dec 2021 Minghui Hu, Yujie Wang, Tat-Jen Cham, Jianfei Yang, P. N. Suganthan

We show that with the help of a content-rich discrete visual codebook from VQ-VAE, the discrete diffusion model can also generate high fidelity images with global context, which compensates for the deficiency of the classical autoregressive model along pixel space.

Neural Implicit 3D Shapes from Single Images with Spatial Patterns

1 code implementation6 Jun 2021 Yixin Zhuang, Yunzhe Liu, Yujie Wang, Baoquan Chen

However, the image features for describing 3D point samplings of implicit functions are less effective when significant variations of occlusions, views, and appearances exist from the image.

Fixing the Teacher-Student Knowledge Discrepancy in Distillation

no code implementations31 Mar 2021 Jiangfan Han, Mengya Gao, Yujie Wang, Quanquan Li, Hongsheng Li, Xiaogang Wang

To solve this problem, in this paper, we propose a novel student-dependent distillation method, knowledge consistent distillation, which makes teacher's knowledge more consistent with the student and provides the best suitable knowledge to different student networks for distillation.

DMCP: Differentiable Markov Channel Pruning for Neural Networks

1 code implementation CVPR 2020 Shaopeng Guo, Yujie Wang, Quanquan Li, Junjie Yan

In DMCP, we model the channel pruning as a Markov process, in which each state represents for retaining the corresponding channel during pruning, and transitions between states denote the pruning process.

Beyond Trade-off: Accelerate FCN-based Face Detector with Higher Accuracy

no code implementations CVPR 2018 Guanglu Song, Yu Liu, Ming Jiang, Yujie Wang, Junjie Yan, Biao Leng

Fully convolutional neural network (FCN) has been dominating the game of face detection task for a few years with its congenital capability of sliding-window-searching with shared kernels, which boiled down all the redundant calculation, and most recent state-of-the-art methods such as Faster-RCNN, SSD, YOLO and FPN use FCN as their backbone.
