Optic clustering
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 … WebSep 13, 2024 · In this section, we are using OPTIC and K-mean clustering algorithms. The goal is to compare the results of the three clustering algorithms against the climate zones of France. You can find the climate zones of France here. Create a new calculated field.
