Researchers have developed a method to predict the performance degradation of radio-frequency impairment detectors when faced with distribution shifts. This approach utilizes in-distribution statistics to forecast how much a detector's accuracy (AUC) will decrease in real-world conditions, a metric often unknown due to scarce labeled field data. The developed ridge model, trained solely on in-distribution score statistics, can predict this "optimism gap" for unseen detectors and impairment classes with significant accuracy, a finding that holds true even when tested on real-world datasets.
