A general framework for multi-step ahead adaptive conformal heteroscedastic time series forecasting

1 code implementation28 Jul 2022 Martim Sousa, Ana Maria Tomé, José Moreira

This paper introduces a novel model-agnostic algorithm called adaptive ensemble batch multi-input multi-output conformalized quantile regression (AEnbMIMOCQR} that enables forecasters to generate multi-step ahead prediction intervals for a fixed pre-specified miscoverage rate in a distribution-free manner.

Improved conformalized quantile regression

no code implementations6 Jul 2022 Martim Sousa, Ana Maria Tomé, José Moreira

To show that this improved version outperforms the classic version of conformalized quantile regression and is more adaptive to heteroscedasticity, we extensively compare the prediction intervals of both in open datasets.
