Cloud-edge Collaboration for Robust Network Embeddings
This paper introduces CC-Net, a novel framework leveraging cloud-edge collaboration for robust node embeddings in multi-view networks. It addresses challenges like capturing implied relations among multiple views and efficiently updating embeddings with topology changes. By decomposing features into common and specific domains and using a cloud-edge architecture, CC-Net avoids full network retraining, significantly enhancing scalability and adaptability. Extensive experiments on real-world datasets confirm its superior performance and effectiveness in generating robust node representations.

Core Architecture of CC-Net
The CC-Net framework employs a novel decomposition and regrouping module to identify both common and view-specific features across multiple sub-networks. This allows for comprehensive node representations that integrate diverse information. By leveraging a cloud-edge paradigm, the system ensures efficient handling of dynamic network changes without extensive retraining, maintaining scalability and robustness.

Dynamic Network Adaptability
The cloud-edge framework is central to CC-Net's ability to adapt to dynamic network topologies without retraining the entire network. The base social network resides in the cloud, while sub-networks operate at the edge. This distributed architecture facilitates real-time processing and efficient updates, significantly reducing computational overhead during node failures or additions, as validated by experiments on new and failed nodes.
