Sklearn optics label
WebbOPTICS (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, … WebbThe OPTICS is first used with its Xi cluster detection method, and then setting specific thresholds on the reachability, which corresponds to DBSCAN. We can see that the …

Webb15 feb. 2024 · The implementation of OPTICS clustering using scikit-learn (sklearn) is straightforward. You can use the OPTICS class from the sklearn.cluster module. Here is an example of how to use it: Python … Webb10 sep. 2024 · 2. i am trying to use sklearn.cluster.OPTICS to cluster an already computed similarity (distance) matrix filled with normalized cosine distances (0.0 to 1.0) but no matter what i give in max_eps and eps i don't get any clusters out. Later on i would need to run OPTICS on a similarity matrix of more than 129'000 x 129'000 items hopefully relying ...
