I've found how to combine pre-built models in one! Googling a little bit more, I've found the answer in the Wekalist forum in Nabble (http://old.nabble.com/bug-request-on-multiple-input-Vote-td32240244.html). To whom it may concern, it's just to use Vote and its option "preBuiltClassifiers" in case you use GUI. In command line, type java -cp weka.jar weka.classifiers.meta.Vote -S 1 -R AVG -P a.model -P b.model -P c.model -t any_training_data -no-cv -d combined_model
I've got hundreds of models I've generated by training J48 with different
sets of training data and I'd like to know if it's possbile to combine them.
I've read in some post in this forum that new versions of WEKA are capable
to accomplish this task, but unfortunately I've not bookmarked this page.
It's worth to emphasize that I've already computed the models.
