WebOPTICS, or Ordering points to identify the clustering structure, is one of these algorithms. It is very similar to DBSCAN, which we already covered in another article. In this article, we'll be looking at how to use OPTICS for … WebUnlike centroid-based clustering, OPTICS does not produce a clustering of a dataset explicitly from the first step. It instead creates an augmented ordering of examples based on the density distribution. This cluster ordering can be used bya broad range of density-based clustering, such as DBSCAN. And besides, OPTICS can provide density
