Graph Self-Supervised Learning: A Survey
نویسندگان
چکیده
Deep learning on graphs has attracted significant interests recently. However, most of the works have focused (semi-) supervised learning, resulting in shortcomings including heavy label reliance, poor generalization, and weak robustness. To address these issues, self-supervised (SSL), which extracts informative knowledge through well-designed pretext tasks without relying manual labels, become a promising trending paradigm for graph data. Different from SSL other domains like computer vision natural language processing, an exclusive background, design ideas, taxonomies. Under umbrella we present timely comprehensive review existing approaches employ techniques We construct unified framework that mathematically formalizes SSL. According to objectives tasks, divide into four categories: generation-based, auxiliary property-based, contrast-based, hybrid approaches. further describe applications across various research fields summarize commonly used datasets, evaluation benchmark, performance comparison open-source codes Finally, discuss remaining challenges potential future directions this field.

A Brief Survey on Semi-supervised Learning with Graph Regularization
In this survey, we go over a few historical literatures on semi-supervised learning problems which apply graph regularization on both labled and unlabeled data to improve classification performance. These semi-supervised methods usually construct a nearest neighbour graph on instance space under certain measure function, and then work under the smoothness assumption that class labels of samples...
متن کاملSupervised Learning of Graph Structure
Graph-based representations have been used with considerable success in computer vision in the abstraction and recognition of object shape and scene structure. Despite this, the methodology available for learning structural representations from sets of training examples is relatively limited. In this paper we take a simple yet effective Bayesian approach to attributed graph learning. We present...
متن کاملGraph-Based Semi-Supervised Learning
While labeled data is expensive to prepare, ever increasing amounts of unlabeled data is becoming widely available. In order to adapt to this phenomenon, several semi-supervised learning (SSL) algorithms, which learn from labeled as well as unlabeled data, have been developed. In a separate line of work, researchers have started to realize that graphs provide a natural way to represent data in ...
