Since 1998 feed-forward networks have been applied for the separation of hadronic WW-decays from background processes measured by the DELPHI collaboration at different center-of-mass energies of the Large Electron Positron collider at CERN. Prior to the publication of the 189 GeV results (1) intensive studies of systematic effects and uncertainties were performed. The methods and results will be discussed and compared to standard selection procedures.
