Separating Stars from Quasars: Machine Learning Investigation Using Photometric Data

Python code to attempt to identify high-redshift quasars using their infrared colours. The program uses a decision tree classifier to learn the quasar and dwarf star distributions in the selected colour spaces, and a subset of new data is used to trial run the code.
