#' Badges
#'
#' Every pre-registered attendee at the 1994 Machine Learning Conference and
#' 1994 Computational Learning Theory Conference received a badge labeled with
#' a "+" or "-".  The labeling was due to some function known only to the badge
#' generator (Haym Hirsh), and it depended only on the attendee's name. The goal
#' for conference attendees was to identify the unknown function used to
#' generate the +/- labeling.

#' ML94/COLT94 Badge Problem. Badges labeled with a "+" or "-" as a function of
#' a person's name. Part of the problem in using an automated program to
#' discover the unknown target function is to decide how to encode names such
#' that the program can be used.  The data below are presented in the form of
#' a +/- label followed by the person's name.  It is up to the learning-system
#' user to decide how to convert this data into something usable by the system
#' (e.g., what attributes to use if your favorite learner requires
#' feature-vector data).
