OneShot uses one confirmed anomaly to weight detector pool

OneShot is a new method for time series anomaly detection. It uses a single confirmed anomaly to score and weight multiple detectors instead of picking just one. The scores from the confirmed anomaly become weights for combining the detectors. Tests on 152 univariate and 73 multivariate series show OneShot outperforms the strongest single detector and simple averaging. Code is available online.
