Automated Lensing Learner: Automated Strong Lensing Identification with a Computer Vision Technique [PDF]
Forthcoming surveys such as the Large Synoptic Survey Telescope (LSST) and Euclid necessitate automatic and efficient identification methods of strong lensing systems. We present a strong lensing identification approach that utilizes a feature extraction
