In e-commerce, recommender systems are the most widely used systems that satisfy the user with personalized recommendations, and they have a significant influence on e-business success. In the new era of artificial intelligence (AI) and deep learning techniques, modern recommender systems have evolved from the classical models of content-based filtration systems to highly sophisticated and accurate models. In this post, we take a closer look at specific optimization techniques that are applied in the context of AI-based recommender systems in the e-commerce industry. We start with the data needed to train these systems and the different ways to collect and clean the data. Next, we delve into getting recommendations and the methods behind them - collaborative filtering (CF), content-based filtering (CB), etc. Next, we explain how deep learning approaches such as natural language processing and neural networks improve the accuracy of these systems. We look at what sort of problems you face while implementing these systems (cold-start issue, data sparsity issues et al) and how are you working to address them. We also consider ethical concerns regarding recommender systems: bias and privacy. Finally, we summarize the various use cases of AI-based recommender systems in e-commerce, including product recommendations, personalized promotions, and user profiling. This paper intends to present a general survey of the techniques which are being state-of-the-art in e-commerce AI recommender systems and a brief discussion of how they can massively boost user satisfaction in unison with business goals.
