Description

Notes: - Additional "background" knowledge is supplied that provides a partial ordering on some of the attribute values. - We are providing this dataset both in its original form and in a form similar to the more typical propositional datasets in our repository. Since the trains dataset records relations between attributes, this transformation was somewhat challenging. However, it may shed some insight on this problem for people who are more familiar with the simple one-instance-per-line dataset format. Hierarchy of values: if (cshape is one of {openrect,opentrap,ushaped,dblopnrect} then cshape is opentop if (cshape is one of {hexagon,ellipse,closedrect,jaggedtop,slopetop, engine} then cshape closedtop Prediction task: Determine concise decision rules distinguishing trains traveling east from those traveling west.
