Abstract Most supervised machine learning methods yielda point prediction for a target, $Y \in \sY$,based on features, $\X \in \sX$. Recently, a large body of work in statistics and machine learning has been devoted to develop methods that are able to quantify the uncertainty over point predictions. These go from prediction regions to conditional density estimators and quantile regression methods. In order for such methods to be useful, they need to be calibrated, that is, they should properly quantify uncertainty. Although several notions of calibration have been developed for different tasks, they only assess the overall validity of an algorithm. Hence, none of these definitions can properly measure local calibration, which can lead to fairness concerns in several practical problems. In this project, we propose an alternative calibration framework that is specially designed to assess and perform local calibration in both regression and classification, with applications in Dengue nowcasting and forecasting models.
