I love Weka for its visual data exploration features (it's great at quickly giving you a mile-high aerial view of the distributions of all your variables).
I have a 0.5gb dataset, and Weka is unable to load it (on a 64-bit Windows PC with 16gb of RAM).
For the Weka fans out there, what's the closest 'visual data exploration' alternative for very large datasets?
(FWIW - I've done all the various things that are recommended when Weka fails at loading a very large dataset, e.g., increasing the Java heap size, etc.)
Update: I tried RapidMiner Basic (it's open source and free), and that worked.
