WEKA J48 decision tree with non linearly separable data -


does weka j48 decision tree classifier support classification problem intrinsically non linearly separable data? in short, j48 either linear or non linear classifier?

in short, j48 either linear or non linear classifier?

  • i don't know.

however, decision boundaries of j48 can made, in way, "stepwise linear". can approximate nonlinear decision boundary if set minnumobjects low enough , set pruning false (= unpruned true).

here visualization of linear boundaries using weka's boundaryvisualizer:

enter image description here

this accessible via small rectangular "weka gui chooser" window. there can load own dataset.

here video explains more details: https://youtu.be/fmxfukykcvg?t=568
