Under the feature columns, could you please clarify on the below part from `Crossed column` section ?
Somewhat counterintuitively, when creating feature crosses, you typically still should include the original (uncrossed) features in your model (as in the preceding code snippet). The independent latitude and longitude features help the model distinguish between examples where a hash collision has occurred in the crossed feature.
I'm not able to grasp how the original features are included alongside the crossed features here. Would it still be 100 x 100 combinations ? If so, how would that look like ? Maybe a short example would help me clear my head.
