Abstract

Predicting customer's next purchase is of paramount importance for online retailers. In this paper, we present a new purchase prediction method to predict customer behavior based on nonparametric Bayesian framework. The proposed method is inspired by topic modeling for text mining. Unlike the conventional methods, we regard customer's purchase as the result of motivations and automatically determine the number of user purchase motivations. Given customer's purchase history, we show that customer's next purchase can be predicted by non-parametric Bayesian model. We apply the model to real-world dataset from Amazon.com and prove it outperforms the traditional methods. Besides that, the proposed method can also determine the number of the motivations owned by users automatically, rendering it a promising approach with a good scalability.
