Incorporating dwell time in session-based recommendations with recurrent Neural networks

Recurrent Neural Networks (RNN) is a frequently used technique for sequence data predictions. Recently, it gains popularity in the Recommender Systems domain, especially for session-based recommendations where naturally, each session is defined as a sequence of clicks, and timestamped data per click is available. In our research, in its early stages, we explore the value of incorporating dwell time into existing RNN framework for session-based recommendations by boosting items above the predefined dwell time threshold. We show improvement in recall@20 and MRR@20 by evaluating the proposed approach on e-commerce RecSys’15 challenge dataset.
