In this competition, you will be given a training set of real noise segments of the Hanford detector during the O3 run, in which gravitational wave models were injected at different signal-to-noise ratios (SNR). Your task is to classify each segment into one of three categories: 1) 0<=SNR<6 2) 6 <=SNR <10 and 3) SNR >= 10.

The injections correspond to binary black hole mergers with non-aligned spins, having masses between 7 and 50 times the solar mass, randomly distributed at different sky localizations and inclinations and in a distance ranges that results in signal to noise ratios up to about 50.
