作者：一元，炼丹笔记四品炼丹师 CAN: Revisiting Feature Co-Action for Click-Through Rate Prediction(ArXiv2020) 背景...本文提出了feature Co-Action Network(CAN)捕获在输入阶段的特征的co-action并且利用交互和共同信息来对最终模型的效果进行提升。...相比之下，CAN比笛卡尔积和结合嵌入的方法取得了更好的效果，这意味着基于网络的CAN机制可以同时学习表示能力和协作能力 解耦研究 ?...Generalization: CAN还是工作的非常好, 具有非常好的泛化性。 工业数据集上的表现 ? CAN在工业数据集上A/B Test上得到了非常大的提升。...小结 在笛卡尔产品模型的启发下，我们提出了一种新的特征交叉范式：Co-Action network，CAN。
