WebCombining HDBSCAN* with DBSCAN¶. While DBSCAN needs a minimum cluster size and a distance threshold epsilon as user-defined input parameters, HDBSCAN* is basically a DBSCAN implementation for varying epsilon values and therefore only needs the minimum cluster size as single input parameter. The 'eom' (Excess of Mass) cluster selection … WebAlthough BERTopic works quite well out of the box, there are a number of hyperparameters to tune according to your use case. This section will focus on important parameters …

I would advise reading through the parameter tuning section of the documentation here as it goes through important parameters of BERTopic, HDBSCAN, and UMAP. All reactions. Web1 mar 2016 · DBSCAN is most cited clustering algorithm according to some literature and it can find arbitrary shape clusters based on density. It has two parameters eps (as neighborhood radius) and minPts (as minimum neighbors to consider a point as core point) which I believe it highly depends on them.
WebHDBSCAN is a clustering algorithm developed by Campello, Moulavi, and Sander . It extends DBSCAN by converting it into a hierarchical clustering algorithm, and then using …
