REPTree - how to interpret resulting model question
Guru
According to training I have obtained this REPTree:
I guess the 173 is the total number of examples fulfilling the "ATT2(10)[2] < 44.85" condition, 56 could be successfull predictions. What is the [84/29].
I would really appreciate any help as I can not google anything on the Internet.
Thanks in advance.
REPTreePlease, could anyone explain to me what e.g. the "(173/56) [84/29]" stands for in the line "ATT2(10)[2] < 44.85 : -1 (173/56) [84/29]"?
============
ATT1 < 0.13
| ATT2 < 44.85 : -1 (173/56) [84/29]
| ATT2 >= 44.85
| | ATT3 < 0.24 : 1 (194/72) [91/45]
| | ATT3 >= 0.24 : -1 (49/15) [21/7]
ATT1 >= 0.13 : -1 (254/71) [140/50]
Size of the tree : 7
