PhD Student
Job description
PhD Researcher in Learning-based control algorithms for avatar animation in dyadic interactions
Job description
Ghent University is a world of its own. Employing more than 15.000 people, it is actively involved in education and research, management and administration, as well as technical and social service provision on a daily basis. It is one of the largest, most exciting employers in the area and offers great career opportunities.
With its 11 faculties and more than 85 departments offering state-of-the-art study programmes grounded in research in a wide range of academic fields, Ghent University is a logical choice for its staff and students.
The IDLab Ghent research group is seeking a highly motivated and talented PhD student to join the distributed machine learning team. Our team focuses on developing efficient machine learning algorithms for perception and control; with diverse applications in industry, robotics, remote sensing and agriculture.
Topic
With the advent of novel VR/XR devices, we envision an increasing number of social interactions with AI-animated avatar. Compared to the limitations of hardware humanoid robots, the bodily and facial expressions of contemporary avatars can be rendered with much more detail, making them a fertile platform for research on human-AI interaction. Meaningful interaction with avatars requires autonomous generation of verbal as well as non-verbal communication. Non-verbal communication involves not only co-gestures that support speech, but also the emission of feedback signals while listening. Whereas Large Language Models provide a mature technology to autonomously generate verbal responses, research on AI-driven generation of non-verbal communication cues is still in its infancy, especially in situations where the avatar is actively listening or where it is providing non-verbal feedback on the performance of the conversation partner.
In this PhD, we want to investigate learning-based control algorithms for animation of non-verbal avatar behavior during a dyadic interaction, in particular a teaching scenario. The control algorithm will be designed in the framework of active inference, an emerging computational principle stating that embodied behavior is the result from variational minimization of free energy.
The research will be contextualized in an industry relevant use case scenario. As an illustrative example, one could consider an avatar is teaching an assembly operation to an operator. Social studies have indicated how the social signals exchanged are indicative for tracking the learning progress of the student. The exact use case will be determined at the start of the project.
Role and responsibilities
This is a PhD project that will be executed in close cooperation with researchers from imec-mict-UGent, a research group focused on unraveling human interactions through technology. In this project, imec-mict-UGent provides expertise in VR environment design, cognitive and experimental psychology, as well as data-driven metrics for communication quality. At a larger scale, this project is situated within the context of the Flanders AI Research Program, allowing the candidate to interact with fellow researchers throughout Flanders.
Your main tasks include:
In addition to your primary research responsibilities, you will actively contribute to the educational mission of our institution by providing support for various courses in areas such as machine learning, reinforcement learning and algorithm design. In addition, you can take on a mentoring role by supervising bachelor and master theses related to the subject of this PhD.
