Researchers have developed a new method called Calibrated Prediction-Powered Inference (CalPPI) to improve semisupervised mean estimation. This technique involves post-hoc calibration of prediction scores using a small labeled dataset before applying them to a larger unlabeled dataset. The method aims to enhance both predictive accuracy and the efficiency of semisupervised estimation, particularly when prediction scores are not perfectly aligned with the outcome scale. Experiments show that CalPPI often outperforms existing methods like PPI and is competitive with or better than AIPW and PPI++. AI
