A new research paper proposes an improved method for comparing algorithms, particularly in the context of A/B testing for online services. The study reveals that traditional A/B testing can sometimes be less accurate than offline evaluation due to a lack of positive correlation in its sample mean estimator. The researchers introduce a novel estimator that intentionally induces this positive correlation by using a hypothetical middle algorithm, thereby reducing critical selection errors. Experiments show this new approach can achieve the same accuracy as existing methods with half the A/B testing data. AI
