What is the actual meaning of these two points in Big Query. I get that in 2nd, maybe, by total cardinality it actually means no. of features. What about point 1?
- If total cardinalities of training features are more than 10,000, batch_gradient_descentstrategy is used.
- If there is over-fitting issue, that is, the number of training examples is less than 10x, where x is total cardinality, batch_gradient_descent strategy is used.
