However, something seems odd to me when looking at the description:
Training set - Total of 25010 instances in a domain of 311,875,200.
Testing set - Total of one million instances in a domain of 311,875,200.
Why is the training set so small? And why is the testing set so big? I thought that normally these sets should be distributed 80%/20%, but this is 2.4%/97.6%.
