%description
An implementation of the 'Evidential Neural Network for Regression' model
recently introduced in Denoeux (2023) <doi:10.1109/TFUZZ.2023.3268200>. In
this model, prediction uncertainty is quantified by Gaussian random fuzzy
numbers as introduced in Denoeux (2023) <doi:10.1016/j.fss.2022.06.004>.
The package contains functions for training the network, tuning
hyperparameters by cross-validation or the hold-out method, and making
predictions. It also contains utilities for making calculations with
Gaussian random fuzzy numbers (such as, e.g., computing the degrees of
belief and plausibility of an interval, or combining Gaussian random fuzzy
numbers).
