#' Portuguese wine quality 
#'
#' The datasets contains red and white variants of the Portuguese "Vinho Verde" wine.
#' These datasets can be viewed as classification or regression tasks. The classes are ordered and not balanced
#' (e.g. there are munch more normal wines than excellent or poor ones). Outlier detection algorithms could be used
#' to detect the few excellent or poor wines. Also, we are not sure if all input variables are relevant.
#'
#' Due to privacy and logistic issues, only physicochemical (inputs) and sensory (the output) variables
#' are available (e.g. there is no data about grape types, wine brand, wine selling price, etc.).
