Query: Should I send this notification? Optimizing push notifications decision
  making by modeling the future   Most recommender systems are myopic, that is they optimize based on the
immediate response of the user. This may be misaligned with the true objective,
such as creating long term user satisfaction. In this work we focus on mobile
push notifications, where the long term effects of recommender system decisions
can be particularly strong. For example, sending too many or irrelevant
notifications may annoy a user and cause them to disable notifications.
However, a myopic system will always choose to send a notification since
negative effects occur in the future. This is typically mitigated using
heuristics. However, heuristics can be hard to reason about or improve, require
retuning each time the system is changed, and may be suboptimal. To counter
these drawbacks, there is significant interest in recommender systems that
optimize directly for long-term value (LTV). Here, we describe a method for
maximising LTV by using model-based reinforcement learning (RL) to make
decisions about whether to send push notifications. We model the effects of
sending a notification on the user's future behavior. Much of the prior work
applying RL to maximise LTV in recommender systems has focused on session-based
optimization, while the time horizon for notification decision making in this
work extends over several days. We test this approach in an A/B test on a major
social network. We show that by optimizing decisions about push notifications
we are able to send less notifications and obtain a higher open rate than the
baseline system, while generating the same level of user engagement on the
platform as the existing, heuristic-based, system.
