    "A linear model with a wide set of crossed-column (co-occurrence) features can memorize the feature interactions, while deep neural networks (DNN) can generalize the feature patterns through low-dimensional dense embeddings learned for the sparse features. [**Wide-and-deep**](https://arxiv.org/abs/1606.07792) learning jointly trains wide linear model and deep neural networks to combine the benefits of memorization and generalization for recommender systems.\n",
