Weka alternative - visual data exploration with a very large dataset

Question

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.

Answer 1

I tried Azure Machine Learning (by Microsoft) and it is very nice. It can easily handle large data sets and has similar to weka pipeline for ML tasks and visualisation. They offer it free for 30 days so you can try it. You can google it or follow this link Azure ML

Answer 2

First I wanted to propose Orange Data Mining Suite.

But then, I know almost for certain that there isn't a Windows version of 64bit NumPy available, which Orange uses, and thus your data probably won't fit in with the 32bit Windows release they provide out of the box. It may be installable if you can find your way around Python well enough, but it may just also prove being easier to switch onto some more productive platform (i.e. GNU/Linux and Macintosh OS X are supported).
