中文简介:
深度学习在解决诸如图像识别(ImageNet)、语音识别、机器翻译等复杂任务方面取得了广泛成功。在个性化推荐系统中,深度学习成功的关键在于它能够在低维密集向量空间中学习用户和物品属性的分布式表示,并将这些属性组合起来,向用户推荐相关的物品。为了解决可扩展性问题,在web规模上实现推荐系统通常利用信息检索系统的组件,例如从用户属性和上下文构建查询的倒排索引,学习排序技术。此外,它依赖于机器学习模型来预测项目的相关性,比如协同过滤。在本教程中,我们介绍了利用深度学习改进推荐系统的方法。本教程分为四个部分:(1)第一部分,我们将概述深度学习中与推荐系统相关的概念,包括序列建模、词嵌入和命名实体识别。(2)在第二部分中,我们将介绍如何使用这些基本构建块来大规模地改进推荐系统。(3)第三部分介绍了LinkedIn大型推荐系统的一些案例研究,以及我们在将深度学习应用于生产环境时面临的一些挑战。 教程链接:
课程简介: Deep learning has been widely successful in solving complex tasks such as image recognition (ImageNet), speech recognition, machine translation, etc. In the area of personalized recommender systems, deep learning has started showing promising advances in recent years. The key to success of deep learning in personalized recommender systems is its ability to learn distributed representations of users’ and items’ attributes in low dimensional dense vector space and combine these to recommend relevant items to users. To address scalability, the implementation of a recommendation system at web scale often leverages components from information retrieval systems, such as inverted indexes where a query is constructed from a user’s attribute and context, learning to rank techniques. Additionally, it relies on machine learning models to predict the relevance of items, such as collaborative filtering. In this tutorial, we present ways to leverage deep learning towards improving recommender system. The tutorial is divided into four parts: (1) In the first part, we will present an overview of concepts in deep learning which are pertinent to recommender systems including sequence modeling, word embedding and named entity recognition. (2) In the second part, we will present how these fundamental building blocks can be used to improve a recommender system at scale. (3) The third part presents a few case studies from large scale recommender systems at LinkedIn and some of the challenges we faced while getting deep learning to work in production.
