Tuning with HDBSCAN

Clustering is a very hard problem because there is never truly a ‘right’ answer when labels do not exist. This is compounded by techniques with various assumptions in place. If a technique is run…

A gentle introduction to HDBSCAN and density-based clustering

“Hierarchical Density-based Spatial Clustering of Applications with Noise” (What a mouthful…), HDBSCAN, is one of my go-to clustering algorithms. It’s a method that I feel everyone should include in…

Understanding HDBSCAN and Density-Based Clustering

A comprehensive top-down introduction to the inner workings of the HDBSCAN clustering algorithm and key concepts of density-based clustering

Lightning Talk: Clustering with HDBScan

I was recently asked to give a lightning talk regarding a clustering algorithm called HDBScan. HDBScan is based on the DBScan algorithm, and like other clustering algorithms it is used to group like…

A Metric for HDBSCAN-Generated Clusters

How can we determine the equivalent DBSCAN ε parameter for HDBSCAN-generated clusters? The image above depicts the minimum spanning tree of distances in an HDBSCAN-generated cluster. Image by the aut...

Geographic Clustering with HDBSCAN

Your smartphone knows when you are at home or the office. At least, mine does, and can even tell me when to leave to get at one of my common destinations on time. We all accept that our smart devices…...

HDBSCAN Clustering with Neo4j

I recently came across the article “How HDBSCAN works” by Leland McInnes, and I was struck by the informative, accessible way he explained a complex machine learning algorithm. Unlike clustering…

A Practical Guide to DBSCAN Method

When I was working on my first data science task and I wanted to use DBSCAN (Density-Based Spatial Clustering of Applications with Noise) for clustering, many times I searched for answers to…

DBSCAN, Explained in 5 Minutes

Fastest implementation in python🐍 Image by author. What’s DBSCAN [1]? How to build it in python? There are many articles covering this topic, but I think the algorithm itself is so simple and intuit...

Easy Analysis of HDF5 Data

There is a data format called HDF5 (Hierarchical Data Format) which is used extensively in scientific research. HDF5 is an interesting format in that it is like a file system within a file, and is…
