Interactive Graph Learning for Multilevel Network Alignment.

Area of Science:

• Network Science
• Graph Theory
• Machine Learning

Background:

• Network alignment identifies node correspondences across networks, crucial for social network analysis and bioinformatics.
• Traditional methods often neglect network properties like scale-free and power-law structures, leading to suboptimal alignment.
• Existing approaches fail to fully leverage multi-level topological and attribute information.

Purpose of the Study:

• To propose an advanced network alignment framework.
• To integrate topological and attribute information across multiple network levels.
• To enhance alignment accuracy by effectively modeling power-law structures.

Main Methods:
