WebApr 1, 2024 · 1. Introduction. Clustering (an aspect of data mining) is considered an active method of grouping data into many collections or clusters according to the similarities of data points features and characteristics (Jain, 2010, Abualigah, 2024).Over the past years, dozens of data clustering techniques have been proposed and implemented to solve data … WebOPTICS (Ordering Points To Identify the Clustering Structure), closely related to DBSCAN, finds core sample of high density and expands clusters from them [1]. Unlike DBSCAN, keeps cluster hierarchy for a variable neighborhood radius. Better suited for usage on large datasets than the current sklearn implementation of DBSCAN.
