Social Network Analysis (SNA) & Graph ML to do Part Segmentation of Point Cloud Data using Community Detection

This repository contains the code (and a sample of data) of a research project at the intersection of SNA, Graph ML, and the built environment. This research encompasses several steps:

1. Importing point cloud data into python.
2. Converting point cloud data to the corresponding Adjacency matrix.
3. Creating an undirected Graph network (using igraph).
4. Analyze the created Graph using different metrics (e.g., centrality measures).
5. Conduct community detection (CD) on the graph using different methods (i.e., Label Propagation, Eigenvector, Infomap, and Components).
6. Visualize and compare the results (of different CD methods)
