Why there are no tumor slides in the validation set?

Hi Arjun. Great work.
Although, I do not get that why you have included only normal tissue patches in your validation set and have not included a single tumor tissue patch? The inception_eval.py evaluates the precision for false positive cases only and does not evaluate the errors that might come due to the false negative cases. Is there a specific rationale behind this that I am missing. Thanks.
