摘要:

将深度学习应用于搜索排名是Airbnb最具影响力的产品改进之一。但是在你启动了一个深度学习模型之后,接下来会发生什么呢?在本文中,我们描述了超越的旅程,讨论了我们所说的改进搜索的ABC:A为架构,B为偏见,C为冷启动。对于架构,我们描述了一个新的排名神经网络,专注于我们现有的DNN超越完全连接的两层网络的过程。在处理排名中的位置偏差时,我们描述了一种新方法,该方法在处理DNN历史上发现具有挑战性的库存方面取得了最重大的改进之一。为了解决冷启动,我们描述了我们对问题的看法以及我们为改善平台上新物品的处理所做的更改。我们希望过渡到深度学习的排名团队会发现这是一个如何在DNN上学习的实际案例研究。

英文摘要:

The application of deep learning to search ranking was one of the most impactful product improvements at Airbnb. But what comes next after you launch a deep learning model? In this paper we describe the journey beyond, discussing what we refer to as the ABCs of improving search: A for architecture, B for bias and C for cold start. For architecture, we describe a new ranking neural network, focusing on the process that evolved our existing DNN beyond a fully connected two layer network. On handling positional bias in ranking, we describe a novel approach that led to one of the most significant improvements in tackling inventory that the DNN historically found challenging. To solve cold start, we describe our perspective on the problem and changes we made to improve the treatment of new listings on the platform. We hope ranking teams transitioning to deep learning will find this a practical case study of how to iterate on DNNs.
