Data scientists face off in LSST machine-learning competition

Data scientists trained computers to pick out useful information from LSST's hi-res snapshots of the universe. A new telescope will take a sequence of hi-res snapshots with the world's largest digital camera, covering the entire visible night sky every few days--and repeating the process for an entire decade. That presents a big data challenge: What's the best way to rapidly and automatically identify and categorize all of the stars, galaxies and other objects captured in these images? To help s...
