Harnessing the power of SOMs for clustering and Attentive Latent Neural Processes for features sampled from within the latent space, we present the pilot results of our analysis on several large surveys from the Optical and X-ray bands including the LSST AGN Data Challenge, Gaia, ZTF, and Swift Surveys. |
