摘要:

具有非线性特征变换的广义线性模型被广泛应用于具有稀疏输入的大规模回归和分类问题。通过广泛的跨产品特征转换的特征交互的泛化是有效的和可解释的,而泛化需要更多的特征工程工作。通过较少的特征工程,深度神经网络可以通过为稀疏特征学习的低维密集嵌入来更好地泛化到看不见的特征组合。然而,当用户-项目交互稀疏且排名高时,具有嵌入的深度神经网络可能过度泛化并推荐不太相关的项目。在本文中,我们提出了宽和深度学习-联合训练的宽线性模型和深度神经网络-结合推荐系统的记忆和泛化的好处。我们在Google Play上对该系统进行了生产和评估,Google Play是一个商业移动应用程序商店,拥有超过10亿活跃用户和超过100万个应用程序。在线实验结果表明,与仅限宽和仅限深的模型相比,宽深模型显著增加了应用程序的获取。我们还在TensorFlow中开源了我们的实现。

英文摘要:

Generalized linear models with nonlinear feature transformations are widely used for large-scale regression and classification problems with sparse inputs. Memorization of feature interactions through a wide set of cross-product feature transformations are effective and interpretable, while generalization requires more feature engineering effort. With less feature engineering, deep neural networks can generalize better to unseen feature combinations through low-dimensional dense embeddings learned for the sparse features. However, deep neural networks with embeddings can over-generalize and recommend less relevant items when the user-item interactions are sparse and high-rank. In this paper, we present Wide & Deep learning---jointly trained wide linear models and deep neural networks---to combine the benefits of memorization and generalization for recommender systems. We productionized and evaluated the system on Google Play, a commercial mobile app store with over one billion active users and over one million apps. Online experiment results show that Wide & Deep significantly increased app acquisitions compared with wide-only and deep-only models. We have also open-sourced our implementation in TensorFlow.
