Definition
Data-driven astronomy leverages advanced computational methods, including machine learning and statistical analysis, to handle the massive volumes of data generated by modern telescopes and surveys. Instead of relying solely on theoretical physics models, researchers use data-driven approaches to classify celestial objects, detect transient events like supernovae, and map dark matter distributions. This field is crucial for managing petabyte-scale datasets from projects like the LSST, enabling discoveries that would be impossible through manual inspection or traditional analytical methods alone.
