WebIterative stratification essentially creates splits while "trying to maintain balanced representation with respect to order-th label combinations". We used to an order=1 for our iterative split which means we cared about providing representative distribution of each tag across the splits. Web2.2 Get the Data 2.2.1 Download the Data.
