特征表示学习在点击率预测中的应用

Feature Representation Learning for Click-through Rate Prediction: A Review and New Perspectives

Fuyuan Lyu, Xing Tang, Dugang Liu, Haolun Wu, Chen Ma, Xiuqiang He, Xue Liu

摘要:

表示学习是机器学习中的一个重要课题。在点击率预测中,大多数特征都表示为嵌入向量,并与模型中的其他参数同时学习。随着CTR模型的发展,特征表示学习成为近年来工业界和学术界研究的热点。本研究旨在从更广阔的视角总结表示学习的特点,为今后的研究做好铺垫。为了实现这样一个目标,我们首先提出了一个分类的特征表示学习以下两个主要问题的研究方法:(i)哪些功能表示和(ii)如何表示这些功能。然后,我们对这两个问题的每种方法进行了详细的描述。最后,审查结论与讨论这一领域的未来发展方向。

英文摘要:

Representation learning has been a critical topic in machine learning. In Click-through Rate Prediction, most features are represented as embedding vectors and learned simultaneously with other parameters in the model. With the development of CTR models, feature representation learning has become a trending topic and has been extensively studied by both industrial and academic researchers in recent years. This survey aims at summarizing the feature representation learning in a broader picture and pave the way for future research. To achieve such a goal, we first present a taxonomy of current research methods on feature representation learning following two main issues: (i) which feature to represent and (ii) how to represent these features. Then we give a detailed description of each method regarding these two issues. Finally, the review concludes with a discussion on the future directions of this field.
