WebAug 17, 2024 · OPTICS is a very interesting technique that has seen a significant amount of discussion rather than other clustering techniques. The main advantage of OPTICS is to finding changing densities with very little parameter tuning. Mainly optics is used for finding density-based clusters in the geographical data very easily.
