Momentary context data is an important source for intelligent decision making towards personalization of mobile phone notifications. We propose a reinforcement learning based personalized notification delivery algorithm, reasoning over momentary context data. Beyond the state of the art, we propose new approaches for faster convergence of the algorithm and jump start of learning performance at the beginning of the learning process. We test our approach in both simulated and real settings trying to optimize the timing of the notifications. Our eventual, practical aim is to make office workers more physically active during the work time. We compare the results obtained for standard and improved algorithms in both testbeds where improved versions yield better results.
The research leading to these results has received funding partially from the European Community’s H2020 Programme under grant agreement no H2020-PHC-689444, POWER2DM project (Predictive Model-Based Decision Support for Diabetes Patient Empowerment) and partially from The Scientific and Technological Research Council of Turkey (TÜBİTAK).
