Grid-based clustering example
WebPerform the clustering using ambiguity limits and then plot the clustering results. The DBSCAN clustering results correctly show four clusters and five noise points. For example, the points at ranges close to zero are clustered with points near 20 m because the maximum unambiguous range is 20 m. WebFeb 17, 2024 · CLIQUE : Grid-Based Subspace Clustering. ...
