Below are some sample datasets that have been used with Auto-WEKA.Each zip has two files, test.arff and train.arff in WEKA's native format. To use these zip files with Auto-WEKA, you need to pass them to an InstanceGenerator that will split them up into different subsets to allow for processes like cross-validation. To perform 10 fold cross-validation with a specific seed, you can use the ...Here's an example (linux command line), assuming the training data is in file.arff: java weka.classifiers.rules.ZeroR -t file.arff This will run ZeroR (zero rules) on the "file.arff" file, show the learned model, and evaluate it using cross-validation.
