title: 'FastKRR: Kernel Ridge Regression using ''RcppArmadillo'''
version: 0.1.2
doi: 10.32614/CRAN.package.FastKRR
abstract: Provides core computational operations in C++ via 'RcppArmadillo', enabling
  faster performance than pure R, improved numerical stability, and parallel execution
  with OpenMP where available. On systems without OpenMP support, the package automatically
  falls back to single-threaded execution with no user configuration required. For
  efficient model selection, it integrates with 'CVST' to provide sequential-testing
  cross-validation that identifies competitive hyperparameters without exhaustive
  grid search. The package offers a unified interface for exact kernel ridge regression
  and three scalable approximations—Nyström, Pivoted Cholesky, and Random Fourier
  Features—allowing analyses with substantially larger sample sizes than are feasible
  with exact KRR. It also integrates with the 'tidymodels' ecosystem via the 'parsnip'
  model specification 'krr_reg', and the S3 method tunable.krr_reg(). To understand
  the theoretical background, one can refer to Wainwright (2019) <https://doi.org/10.1017/9781108627771>.
