DCN was designed to learn explicit and bounded-degree cross features more effectively. ![]() Traditional feed-forward multilayer perceptron (MLP) models are universal function approximators however, they cannot efficiently approximate even 2nd or 3rd-order feature crosses. ![]() Manual feature engineering or exhaustive search. Identifying effective feature crosses in this setting often requires What are the challenges in learning feature crosses? In Web-scale applications, data are mostly categorical, leading to large and sparse feature space.
