+ *     The perceptron is an algorithm for supervised learning of
+ *     binary classifiers (functions that can decide whether an
+ *     input, represented by a vector of numbers, belongs to some
+ *     specific class or not). It is a type of linear classifier,
+ *     i.e. a classification algorithm that makes its predictions based
+ *     on a linear predictor function combining a set of weights with
+ *     the feature vector.
