[Objective] This paper aims to predict online customers’ future purchases based on their previous shopping behaviors.[Methods] We proposed a new product recommendation approach based on multi-head self-attention neural networks. Our method captured the relationship and attributes of items checked out by specific customers.Finally, we generated the recommended lists using recurrent neural networks with attentions.[Results] We examined the proposed approach on three real-world data sets and yielded better F1 values than existing methods (2% higher).[Limitations] The diversity of the recommended lists needs more analysis.[Conclusions] The multi-head self-attention mechanism is an effective way to model shopping behaviors and create better recommendations for the consumers.
