abstract: Implementation of the Dual Feature Reduction (DFR) approach for the Sparse
  Group Lasso (SGL) and the Adaptive Sparse Group Lasso (aSGL) (Feser and Evangelou
  (2024) <https://doi.org/10.48550/arXiv.2405.17094>). The DFR approach is a feature
  reduction approach that applies strong screening to reduce the feature space before
  optimisation, leading to speed-up improvements for fitting SGL (Simon et al. (2013)
  <https://doi.org/10.1080/10618600.2012.681250>) and aSGL (Mendez-Civieta et al.
  (2020) <https://doi.org/10.1007/s11634-020-00413-8> and Poignard (2020) <https://doi.org/10.1007/s10463-018-0692-7>)
  models. DFR is implemented using the Adaptive Three Operator Splitting (ATOS) (Pedregosa
  and Gidel (2018) <https://doi.org/10.48550/arXiv.1804.02339>) algorithm, with linear
  and logistic SGL models supported, both of which can be fit using k-fold cross-validation.
  Dense and sparse input matrices are supported.
