面向潜在客户的智能手机推荐系统
A Hybrid Recommender System for Recommending Smartphones to Prospective Customers
摘要：
推荐系统是机器学习系统的一个子类，它采用复杂的信息过滤策略来减少搜索时间并向任何特定用户推荐最相关的项目。混合推荐系统将多种推荐策略以不同的方式结合起来，以发挥它们的互补优势。一些混合推荐系统结合了协同过滤和基于内容的方法来构建更健壮的系统。在本文中，我们提出了一个混合推荐系统，它结合了交替最小二乘（ALS）的协同过滤与深度学习，以提高推荐性能，以及克服与协同过滤方法，特别是有关其冷启动问题的限制。从本质上讲，我们使用ALS（协同过滤）的输出来影响深度神经网络（DNN）的推荐，该网络在大数据处理框架中结合了特征，上下文，结构和顺序信息。我们已经进行了几个实验，在测试所提出的混合架构的有效性，在推荐智能手机给潜在客户，并比较其性能与其他开源路由器。结果表明，该系统的性能优于现有的几个混合推荐系统。
英文摘要：
Recommender Systems are a subclass of machine learning systems that employ sophisticated information filtering strategies to reduce the search time and suggest the most relevant items to any particular user. Hybrid recommender systems combine multiple recommendation strategies in different ways to benefit from their complementary advantages. Some hybrid recommender systems have combined collaborative filtering and content-based approaches to build systems that are more robust. In this paper, we propose a hybrid recommender system, which combines Alternating Least Squares (ALS) based collaborative filtering with deep learning to enhance recommendation performance as well as overcome the limitations associated with the collaborative filtering approach, especially concerning its cold start problem. In essence, we use the outputs from ALS (collaborative filtering) to influence the recommendations from a Deep Neural Network (DNN), which combines characteristic, contextual, structural and sequential information, in a big data processing framework. We have conducted several experiments in testing the efficacy of the proposed hybrid architecture in recommending smartphones to prospective customers and compared its performance with other open-source recommenders. The results have shown that the proposed system has outperformed several existing hybrid recommender systems.
