You are all cordially invited to the AMLab seminar on Tuesday **May 29** at 16:00 in C3.163, where **Diederik Roijers** (VU) will give a talk titled “**Multiple objectives: because we (should) care about the user**”. Afterwards there are the usual drinks and snacks!

**Abstract**: Multi-objective reinforcement learning is on the rise. In this talk, we discuss why multi-objective models and methods are a natural way to model real-world problems, can be highly beneficial, and can be essential if we want optimise for actual users. First, we discuss both the intuitive and formal motivation for multi-objective decision making. Then, we introduce the utility-based approach, in which we show we can make better decisions by putting user utility at the centre of our models and methods. And finally, we discuss two example methods for two different scenarios for using multi-objective models and methods, as well as open challenges.
