In recent years, unsupervised multiplex graph representation learning(UMGRL) has received increasing research interest, which aims to learn discriminative node features from the multiplex graphs supervised by data without the guidance of labels. Although these designed UMGRL methods have obtained great success in various graph-related tasks, most existing UMGRL models still have the following issues: highly depending on complex self-supervised strategies(i.e., data augmentation,pretext tasks, and negative pairs sampling), restricted receptive fields, and only aggregating low-frequency information between nodes. In this paper, we propose a simple unsupervised multiplex graph diffusion network(UMGDN) with the aid of multi-level canonical correlation analysis to solve the above issues. Specifically, we first decouple the feature transform and propagation processes of the graph convolution layer to further improve the generalization of the learnable parameters. And then, we propose adaptive diffusion propagation to capture long-range dependency relationships between nodes, not the local neighborhood interactions. Finally, a multi-level canonical correlation analysis loss on both the feature transform and propagation processes is proposed to maximize the correlation of the same node features from multiple graphs for guiding model optimization. Compared to the existing UMGRL models, our proposed UMGDN does not need to introduce any data augmentation, negative pairs sampling techniques, complex pretext tasks, and also adaptively aggregates the optimal frequency information between nodes to generate more robust node embeddings. Extensive experiments on four popular datasets and two graph-related tasks demonstrate the effectiveness of the proposed method.

韩进海运有限公司于2016年9月1日在韩国进入破产重整程序,成为迄今为止全球最大的航运企业破产案。破产程序启动后,韩进海运的破产管理人短期内向多个国家提出破产保护申请,对相关国家跨界破产立法的承认与救济制度进行了实践检验。在韩进破产案中,各国对于韩国程序实际给予的救济体现了它们对一项外国主要破产程序不同的协助程度及各异的法理依据。而各国在韩进破产案中的破产合作,对于中国未来构建跨界破产承认与救济制度提供了宝贵的借鉴。在目前的法律框架下,应从推定互惠或先行给惠的角度解释《中华人民共和国企业破产法》第5条中的"互惠要求"。从长远看,中国则应参考联合国国际贸易法委员会跨界破产示范法及欧盟破产程序规则等文件构建系统的跨界破产制度。
