Is it possible to save the best classifier through one of the .model files located in the temporary folder?

I would like to save one of these files to use in the pentaho data integration pdi PMI but I'm not sure which file is the correct one (I mean the best classifier indicated in the weka plugin report).

Thanks ! Emannuel Roque

You can save the best classifier by saving the model when Auto-WEKA completed its run, just like for any other WEKA classifier. Is this what you're looking for?

Thanks for your answer.

That is what I normally do but I received some error messages when I try to load the model file saved from the autoweka tab on weka classifier tab.

I tried to train a model in the classifier tab using the parameters shown in the autoweka tab report on the original classifier.

It was difficult to get the parameters match and the result was very different (I know that there may be a difference in the results for several reasons).

I then considered that it would be a more efficient pipeline to take advantage of a .model file in the temporary folder. Since the best model is certainly there and I will use them in pdi.

I tried to load some model files in the temp folder into the tab classifier and it was working. However, none was the better one and it takes too much time to test all.

Thnaks again. Emannuel

Hmm, you might be able to get the best model from the timestamp of the file, but Auto-WEKA doesn't explicitly keep track of this unfortunately.
