DiffusionEdge: Diffusion Probabilistic Model for Crisp Edge Detection

1 code implementation4 Jan 2024 Yunfan Ye, Kai Xu, Yuhang Huang, Renjiao Yi, Zhiping Cai

With the recent success of the diffusion probabilistic model (DPM), we found it is especially suitable for accurate and crisp edge detection since the denoising process is directly applied to the original image size.

RayMVSNet++: Learning Ray-based 1D Implicit Fields for Accurate Multi-View Stereo

no code implementations16 Jul 2023 Yifei Shi, Junhua Xi, Dewen Hu, Zhiping Cai, Kai Xu

In particular, we propose RayMVSNet which learns sequential prediction of a 1D implicit field along each camera ray with the zero-crossing point indicating scene depth.

RARE: Robust Masked Graph Autoencoder

no code implementations4 Apr 2023 Wenxuan Tu, Qing Liao, Sihang Zhou, Xin Peng, Chuan Ma, Zhe Liu, Xinwang Liu, Zhiping Cai

To address this issue, we propose a novel SGP method termed Robust mAsked gRaph autoEncoder (RARE) to improve the certainty in inferring masked data and the reliability of the self-supervision mechanism by further masking and reconstructing node samples in the high-order latent feature space.

Revisiting Initializing Then Refining: An Incomplete and Missing Graph Imputation Network

no code implementations15 Feb 2023 Wenxuan Tu, Bin Xiao, Xinwang Liu, Sihang Zhou, Zhiping Cai, Jieren Cheng

With the development of various applications, such as social networks and knowledge graphs, graph data has been ubiquitous in the real world.

STEdge: Self-training Edge Detection with Multi-layer Teaching and Regularization

1 code implementation13 Jan 2022 Yunfan Ye, Renjiao Yi, Zhiping Cai, Kai Xu

In particular, we impose a consistency regularization which enforces the outputs from each of the multiple layers to be consistent for the input image and its perturbed counterpart.

Video Abnormal Event Detection by Learning to Complete Visual Cloze Tests

1 code implementation5 Aug 2021 Siqi Wang, Guang Yu, Zhiping Cai, Xinwang Liu, En Zhu, Jianping Yin

With each patch and the patch sequence of a STC compared to a visual "word" and "sentence" respectively, we deliberately erase a certain "word" (patch) to yield a VCT.

Deep Fusion Clustering Network

1 code implementation15 Dec 2020 Wenxuan Tu, Sihang Zhou, Xinwang Liu, Xifeng Guo, Zhiping Cai, En Zhu, Jieren Cheng

Specifically, in our network, an interdependency learning-based Structure and Attribute Information Fusion (SAIF) module is proposed to explicitly merge the representations learned by an autoencoder and a graph autoencoder for consensus representation learning.

Multi-View Spectral Clustering with High-Order Optimal Neighborhood Laplacian Matrix

no code implementations31 Aug 2020 Weixuan Liang, Sihang Zhou, Jian Xiong, Xinwang Liu, Siwei Wang, En Zhu, Zhiping Cai, Xin Xu

Multi-view spectral clustering can effectively reveal the intrinsic cluster structure among data by performing clustering on the learned optimal embedding across views.

Modeling Dense Cross-Modal Interactions for Joint Entity-Relation Extraction

no code implementations1 Jul 2020 Shan Zhao, Minghao Hu, Zhiping Cai, Fang Liu

The network is carefully constructed by stacking multiple attention units in depth to fully model dense interactions over token-label spaces, in which two basic attention units are proposed to explicitly capture fine-grained correlations across different modalities (e. g., token-to-token and labelto-token).
