The classify panel lets you designate a class, and FilteredClassifier lets you select both a filter and a classifier to apply. Instead, you can apply this filter by using the FilteredClassifier in the classify panel. Allowing you to do so would give biased results. You cannot use the DiscretizeFilter in the preprocess panel of the Explorer.Note also that there can be large differences in execution time between different virtual machines. This can speed things up quite significantly. For maximum enjoyment, use a virtual machine that incorporates a just-in-time compiler.To set both the maximum Java heap and stack size to 100,000,000 bytes. However, you can extend the memory available for the virtual machine by setting appropriate options. Usually this is much less than the amount of RAM in your computer. Most Java virtual machines only allocate a certain maximum amount of memory to run Java programs.Apparently some web browsers have trouble downloading Weka.
