Part of the project: Ecologically rational strategy selection

How do people, when faced with a cognitive or behavioral task, select strategies that allow them to solve the task in a manner that matches their available resources? To address this question, the project will investigate how organisms infer the anticipated accuracy and costs associated with candidate strategies and how, when choosing from among the toolbox of available strategies, the consideration of the implementation costs is attuned to the resources that are available to the organism. These questions will be investigated both for strategies for decision making under risk and for exploration strategies, and both with human and robot participants.

Project Leads: Oliver Brock, Thorsten Pachur

Description of the (post)doctoral project

Robots (just like biological agents) operating in partially unknown environments must be able to acquire information about the world from their own interactions. In this project, we will investigate strategies for exploration of unknown environments for knowledge acquisition and problem solving. We will also investigate how a robot should choose between strategies based on characteristics of the task and the environment. The strategies themselves and the meta-strategy to switch between them must appropriately balance cost against task success, given uncertain knowledge about the environment. The project will employ state-of-the-art machine learning, such as particular differentiable programming, to represent and learn strategies and meta-strategies. The successful candidate will work together with cognitive scientists and psychologists as well as behavioral ecologists to exploit insights from humans and animals solving similar tasks. At the same time, experimental results from robots will be used to inform human and animal experiments in the other disciplines.
