Research and Application on the Relay Protection Setting Comparison System Based on Fuzzy Matching

2020

Correct relay protection setting is essential to the relay protection correct operation and the safe operation of power grid. Currently, protection setting check still adopts the traditional manual checking mode, which depends on individual technical …

M-Mix

2022 · Proceedings of the 28th ACM SIGKDD Conference on Knowledge Discovery and Data Mining

Negative pairs, especially hard negatives as combined with common negatives (easy to discriminate), are essential in contrastive learning, which plays a role of avoiding degenerate solutions in the sense of constant representation across different instances. …

KGAT

2019

To provide more accurate, diverse, and explainable recommendation, it is compulsory to go beyond modeling user-item interactions and take side information into account. Traditional methods like factorization machine (FM) cast it as a supervised learning …

Towards Deeper Graph Neural Networks

2020

Graph neural networks have shown significant success in the field of graph representation learning. Graph convolutions perform neighborhood aggregation and represent one of the most important graph operations. Nevertheless, one layer of these neighborhood aggregation …

Cross Domain Recommendation via Bi-directional Transfer Graph Collaborative Filtering Networks

2020

Data sparsity is a challenge problem that most modern recommender systems are confronted with. By leveraging the knowledge from relevant domains, the cross-domain recommendation technique can be an effective way of alleviating the data sparsity …
