BEST: A Nonparametric, Multiwavelength Detector for Faint SETI Signals

To the point

BEST is a nonparametric SETI detector that flags unusual beacon-like signals in high-dimensional, multiwavelength data and provides a distance-like measure, outperforming Mahalanobis in near-infrared tests and scaling better with more wavelengths.

Nonparametric Approach to Weak Signal Detection in the Search for Extraterrestrial Intelligence (SETI)

It might be easier for intelligent extraterrestrial civilizations to be found when they mark their position with a bright laser beacon. Given the possible distances involved, however, it is likely that weak signal detection techniques would still be
