Community Detection Techniques

Community detection techniques identify groups within a network where nodes (such as people, web pages, or organizations) are more densely connected to each other than to the rest of the network. Imagine a social network where friends form tight-knit circles; these circles are communities. Techniques like modularity optimization or clustering analyze the connections to find these groups automatically. They help us understand the structure, identify influential nodes, or detect hidden patterns, and are used in social media analysis, biology, and recommendation systems, making complex networks easier to interpret and analyze.
