abstract: 'Classification using Richard A. Harshman''s Parallel Factor Analysis-1
  (Parafac) model or Parallel Factor Analysis-2 (Parafac2) model fit to a three-way
  or four-way data array. See Harshman and Lundy (1994): <https://doi.org/10.1016/0167-9473(94)90132-5>.
  Classification using principal component analysis (PCA) fit to a two-way data matrix
  is also supported. Uses component weights from one mode of a Parafac, Parafac2,
  or PCA model as features to tune parameters for one or more classification methods
  via a k-fold cross-validation procedure. Allows for constraints on different tensor
  modes. Allows for inclusion of additional features alongside features generated
  by the component model. Supports penalized logistic regression, support vector machine,
  random forest, feed-forward neural network, regularized discriminant analysis, and
  gradient boosting machine. Supports binary and multiclass classification. Predicts
  class labels or class probabilities and calculates multiple classification performance
  measures. Uses the ''clue'' package to align Parafac or Parafac2 models across data
  splits in the cross-validation procedure. Calculates classification importance of
  individual features using permutation feature importance. Implements parallel computing
  via the ''foreach'', ''doParallel'', and ''doRNG'' packages.'
