Prepare for the quiz
Before starting the quiz we suggest you reproduce what Ian did in the video, using the LED24 data in the Command Line interface.
Make a test file with 100,000 instances (you should probably precede all filenames below with an appropriate directory specification):
java weka.datagenerators.classifiers.classification.LED24 -n 100000 -o test.arff
Make a training file with 10,000,000 instances:
java weka.datagenerators.classifiers.classification.LED24 -n 10000000 -o train.arff
java weka.classifiers.bayes.NaiveBayesUpdateable -t train.arff -T test.arff
(this will take a few minutes)
Verify that Weka runs out of memory if cross-validation is attempted:
java weka.classifiers.bayes.NaiveBayesUpdateable -t train.arff
Weka will become unresponsive, although you will probably not get an error message.
If you feel brave, repeat the exercise with a 100,000,000-instance training file.
