This project contains a simple implementation of DBSCAN intended to illustrate how the algorithm works. It was written to go along with my blog post here.
My implementation can be found in
scikit-dbscan-example.py, I run both my implementation and the scikit-learn implementation on a dataset and confirm that the resulting labels match.
To improve the performance of my implementation, you would want to use matrix-vector operations to perform the distance calculations (instead of calculating each distance individually in a for-loop).
