   Many thanks for reply.  What I have now is probably like a decision   
   tree since I have a set of (known) reliability metrics and am seeting   
   threshold for them based upon a training set.  However I think a   
   decision tree forms hypercubes (if the metrics are orthogonal).  I   
   would prefer a hypersurface, or perhaps a hyperplane.  However, I will   
   look into Support Vector Machines.   
      
   Thanks again,   
   Peter.
