Discret2Di -- Deep Learning based Discretization for Model-based
  Diagnosis
Lukas Moddemann Henrik Sebastian Steude Alexander Diedrich Oliver Niggemann
Consistency-based diagnosis is an established approach to diagnose technical
applications, but suffers from significant modeling efforts, especially for
dynamic multi-modal time series. Machine learning seems to be an obvious
solution, which becomes less obvious when looking at details: Which notion of
consistency can be used? If logical calculi are still to be used, how can
dynamic time series be transferred into the discrete world?
  This paper presents the methodology Discret2Di for automated learning of
logical expressions for consistency-based diagnosis. While these logical
calculi have advantages by providing a clear notion of consistency, they have
the key problem of relying on a discretization of the dynamic system. The
solution presented combines machine learning from both the time series and the
symbolic domain to automate the learning of logical rules for consistency-based
diagnosis.
