%description
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):
<doi:10.1016/0167-9473(94)90132-5>. Uses component weights from one mode
of a Parafac or Parafac2 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. 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. Implements parallel computing via the 'parallel' and
'doParallel' packages.
