From: Building efficient fuzzy regression trees for large scale and high dimensional problems

Problem DFRT DRT
Training Test Training Test
\(f_1\) 1.5043 1.6654 2.3337 2.8851
\(f_{19}\) 6.5671 7.3154 8.5149 12.1510
\(f_2\) 3.1378 3.2097 3.8151 3.8242
\(f_4\) 4.2888 4.2988 4.5396 5.3521
  1. The best results for each dataset have been emphasized in italic font
  2. The results have to be multiplied by \(10^{22}\), \(10^{22}\), \(10^5\) and \(10^{33}\) for \(f_1\), \(f_{19}\), \(f_2\) and \(f_4\) respectively
