Prediction Intervals: Split Normal Mixture from Quality-Driven Deep Ensembles

1 code implementation19 Jul 2020 Tárik S. Salem, Helge Langseth, Heri Ramampiaro

The ensembled prediction intervals are aggregated as a split normal mixture accounting for possible multimodality and asymmetricity of the posterior predictive distribution, and resulting in prediction intervals that capture aleatoric and epistemic uncertainty.
