    +## Description
    +
    +The polynomial base feature mapper maps a vector into the polynomial feature space of
degree $d$.
    +The dimension of the input vector determines the number of polynomial factors whose values
are the respective vector entries.
    +Given a vector $(x, y, z, \ldots)^T$ the resulting feature vector looks the following:
