Research Interests

Personalized Trust, Trust Building, Adaptable Persuasiveness, Virtual Agents, Reinforcement Learning

Argumentations skills are key skills that virtual agents should also be aware of. Argumentation is "the action or process of reasoning systematically in support of an idea, action or theory.". Arguing or debating agents can learn logical argumentation structures, optimize them and win debates in so-called Argumentation Games (Markov Games). However, it can often be more important how to present arguments: Gestures, Gaze and Voice often play a more important role than the argument itself. My research focus is on Argumentation Games between agents and the exploration of how persuasiveness can autonomously be optimized using Reinforcement Learning so as to learn the best "game strategy". Especially the aspect of whether or not agents can be persuasive using the right behavior even if they are losing the "game" is of high interest.

Projects

EVA How to Win Arguments - Empowering Virtual Agents to Improve their Persuasiveness

In this project, agents will learn argumentation strategies in debates using Reinforcement Learning that will be presented along with behavioral multimodal strategies. We aim to explore the agents' perceieved credibility and whether or not different strategies change their credibility perceived by human users.

Theses and Student Projects

I supervise students interested in topics related to Multimodal Persuasion, Argumentation Games, Virtual Agents, and/or Reinforcement Learning. Please send me an e-mail with either an own topic suggestion or ask for an appointment. I like to regard Project-, Practial modules work as a first step towards identifying a potential follow-up Bachelor's or Master's thesis. Topics are similiar to Bachelor's or Master's theses topics but less focussed and more explorative. Theses can either be written in English or German.
