use clustering to color star data in H-R diagram subset
Using Machine Learning in an HR Diagram
This worksheet is a quick exploration of clustering of unlabeled data to classify stars in a Herzsprung-Russell Diagram (HRD) for a sample set of stars.
In this simple test, two clusters of stars are identified. I think a more sophisticated approach is needed for the other customary groups.
Clustering code is from the scikit-learn Python package.
