Inclusive B-hadron reconstuction using neural networks in DELPHI — •Gary Barker, Zoltan Albrecht, Thomas Allmendinger, Michael Feindt, Christian Haag, and Markus Moch — Institut f"ur experimentelle Kernphysik, Engesserstr.7, 76128 Karlsruhe

Neural network techniques are used extensively in the inclusive reconstruction of B-hadron species from data taken with the DELPHI experiment at LEP. We report on recent improvements to, and extensions of, these techniques for the identification of all B-species and emphasize their use in on-going B-physics analyses at DELPHI.
