I have run gain ratio attributeSelection on weka and also run gain ratio attributeSelection from Java machine learning library
" https://sourceforge.net/p/java-ml/java-ml-code/ci/a25ddde7c3677da44e47a643f88e32e2c8bbc32f/tree/net/sf/javaml/featureselection/scoring/"
The results in term of attribute score and order is quiet different , is this related to diversity discretization method used in both ?
For example,
Gain ratio with discretization method A:
0.509 1671
0.432 765
0.425 249
0.396 625
0.393 493
0.369 1423
0.345 1772
0.344 267
0.344 245
0.335 1042
0.33 513
Gain ratio with discretization method B :
765 0.291676685
493 0.280632207
1411 0.272024568
1423 0.264074648
249 0.24425128
897 0.238272511
1967 0.205044156
1772 0.203703632
1843 0.201867619
245 0.201800878
