PhD student position in Neuro-Symbolic Synthesis and Reinforcement Learning

Ref REF 2022-0881

In this project we study a new approach to synthesis of efficient communication schemes in multi-agent systems, trained via reinforcement learning. We combine symbolic methods with machine learning, in what is referred to as a neuro-symbolic system, where a neural network learns to produce programs in a symbolic language to solve a task at hand. We believe this combination of neural and symbolic methods will be an important next step in the development of AI beyond todays capabilities.

This project is a collaboration between researchers at the division of Data Science and AI at Chalmers and the Center for Linguistic Theory and Studies in Probability (CLASP) at Gothenburg University.

Information about the department and the project
This project touches on several fields, not only AI and computer science but also linguistics and cognitive science. We place our research in a multi-agent context as we consider language learning a collaborative task rather the something that happens entirely in isolation, and take inspiration from studies on human communication in collaborative settings. Agents will not be restricted to use only primitives provided as input, but interactions will be interleaved with (symbolic) steps to extend and revise their current language with novel higher-level concepts, allowing for generalisation and more informative messages.

To get an idea of the project, the applicant might want to read this recent paper, which reports on a pilot study for what we will now develop further:
Towards Learning Abstractions via Reinforcement Learning. E. Jergéus, L. Karlsson Oinonen, E. Carlsson and M. Johansson. 8th Int. Workshop on Artificial Intelligence and Cognitive Science (2022).

The PhD student will be part of a new group forming around research on neuro-symbolic systems led by Dr. Moa Johansson, and will also work closely with a post-doctoral researcher. The group belong to the division of Data Science and AI which spans both machine learning and symbolic AI. Chalmers is one of the leading technical universities in Sweden, and its Computer Science department is one of the best and largest in the country.

Major responsibilities
We are looking for a PhD student with an interest in neuro-symbolic AI (machine learning and symbolic methods) to work as a researcher on this project, which will include both implementation work and experimentation.

The PhD position is funded for five years, of which 80% is research and 20% is teaching.

Qualifications
The candidate should have (or shortly be about to finish) a MSc degree in e.g. Computer Science, AI, computational linguistics, computational cognitive science, mathematics or other relevant fields.

The position requires sound verbal and written communication skills in English. If Swedish is not your native language, Chalmers offers Swedish courses.

Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.

We offer
Chalmers offers a cultivating and inspiring working environment in the coastal city of Gothenburg
