We implemented a random forest and a dimension reduction algorithm called UMAP to classify and analyse 111 million sources from the Sloan Digital Sky Survey (SDSS) based on their photometry. These sources did not have the spectroscopic observations traditionally required for classification, but our method still enabled us to find 2 million new active supermassive black holes.
