#58 SMOreg fails ("Cant handle string attr" but only num feats)

[Martin Gütlein]

Hi Nina, Hi Vedrin,

dataset http://opentox.informatik.uni-freiburg.de/dataset/1974 has only numeric attributes, but SMOreg fails with Cannot handle string attributes!

example:

curl -X POST -d dataset_uri="http://opentox.informatik.uni-freiburg.de/dataset/1974" -d prediction_feature="http://apps.ideaconsult.net:8080/ambit2/feature/930146" http://apps.ideaconsult.net:8080/ambit2/algorithm/SMOreg

-> task fails:
Name: Apply SMOreg: Sequential Minimal Optimization algorithm for training a Support Vector regression to http://opentox.informatik.uni-freiburg.de/dataset/1974
Status:Error
Error: weka.core.UnsupportedAttributeTypeException: weka.classifiers.functions.SMOreg: Cannot handle string attributes! :
