A Delta Debugger for ILP Query Execution
Because query execution is the most crucial part of Inductive Logic
Programming (ILP) algorithms, a lot of effort is invested in developing faster
execution mechanisms. These execution mechanisms typically have a low-level
implementation, making them hard to debug. Moreover, other factors such as the
complexity of the problems handled by ILP algorithms and size of the code base
of ILP data mining systems make debugging at this level a very difficult job.
In this work, we present the trace-based debugging approach currently used in
the development of new execution mechanisms in hipP, the engine underlying the
ACE Data Mining system. This debugger uses the delta debugging algorithm to
automatically reduce the total time needed to expose bugs in ILP execution,
thus making manual debugging step much lighter.Comment: Paper presented at the 16th Workshop on Logic-based Methods in
