Error with duplicate bin ranges #62

Closed cibic89 closed 6 years ago

cibic89 commented 6 years ago

I get this error: A duplicate bin range was detected. Try increasing the bin range precision.

Classification problem with 62 numerical inputs.

This is the dump from the console: [Thread-146] INFO weka.classifiers.meta.AutoWEKAClassifier - classifier: weka.classifiers.meta.RandomCommittee, arguments: [-I, 56, -S, 1, -W, weka.classifiers.trees.RandomForest, --, -I, 8, -K, 0, -depth, 0], attribute search: null, attribute search arguments: [], attribute evaluation: null, attribute evaluation arguments: [] java.lang.IllegalArgumentException: A duplicate bin range was detected. Try increasing the bin range precision.

I have another instance with Kappa as the metric and it works fine? UPDATE: same problem. I suspect it's the outliers in the data and this suggests a fix is to increase digit precision when starting auto-weka
