Published in 2019 at "Soft Computing"

DOI: 10.1007/s00500-017-2822-1

Abstract: This article proposes a nearest neighbors—differential evolution (NNDE) short-term forecasting technique. The values for the parameters time delay $$\tau $$τ, embedding dimension m, and neighborhood size $$\epsilon $$ϵ, for nearest neighbors forecasting, are optimized using… read more here.

Published in 2020 at "International Journal of Forecasting"

DOI: 10.1016/j.ijforecast.2019.06.003

Abstract: Parametric quantile regression is a useful tool for obtaining probabilistic energy forecasts. Nonetheless, traditional quantile regressions may be complicated to obtain using complex data mining techniques (e.g., artificial neural networks), since they are trained using… read more here.
