Contrastive Disentangled Learning on Graph for Node Classification

no code implementations20 Jun 2023 Xiaojuan Zhang, Jun Fu, Shuang Li

Inspired by the success of contrastive learning, we propose a novel framework for contrastive disentangled learning on graphs, employing a disentangled graph encoder and two carefully crafted self-supervision signals.

Variational Disentangled Graph Auto-Encoders for Link Prediction

no code implementations20 Jun 2023 Jun Fu, Xiaojuan Zhang, Shuang Li, Dali Chen

The proposed framework infers the latent factors that cause edges in the graph and disentangles the representation into multiple channels corresponding to unique latent factors, which contributes to improving the performance of link prediction.

Scale Guided Hypernetwork for Blind Super-Resolution Image Quality Assessment

1 code implementation4 Jun 2023 Jun Fu

In this paper, we reveal that the scale factor has a statistically significant impact on subjective quality scores of SR images, indicating that the scale information can be used to guide the task of blind SR IQA.

A Close Look at Few-shot Real Image Super-resolution from the Distortion Relation Perspective

no code implementations25 Nov 2021 Xin Li, Xin Jin, Jun Fu, Xiaoyuan Yu, Bei Tong, Zhibo Chen

Under this brand-new scenario, we propose Distortion Relation guided Transfer Learning (DRTL) for the few-shot RealSR by transferring the rich restoration knowledge from auxiliary distortions (i. e., synthetic distortions) to the target RealSR under the guidance of distortion relation.
