Belle Lab

The Lab carries out research in artificial intelligence, by unifying learning and logic, with a recent emphasis on explainability and ethics.

We are motivated by the need to augment learning and perception with high-level structured, commonsensical knowledge, to enable systems to learn faster and more accurate models of the world. We are interested in developing computational frameworks that are able to explain their decisions, modular, re-usable, and robust to variations in problem description. A non-exhaustive list of topics include:

  • probabilistic and statistical knowledge bases
  • ethics and explainability in AI
  • exact and approximate probabilistic inference
  • statistical relational learning and causality
  • unifying deep learning and probabilistic learning methods
  • probabilistic programming
  • numerical optimization
  • automated planning and high-level programming
  • reinforcement learning and learning for automated planning
  • cognitive robotics
  • automated reasoning
  • modal logics (knowledge, action, belief)
  • multi-agent systems and epistemic planning
  • integrating causality and learning

For example, our recent work has touched upon:

MSc Students:

If you are an Informatics MSc student at the University of Edinburgh, I supervise a number of theses on above topics. See, for example, the publications of other MSc students, including Stefanie Speichert (ILP in hybrid domains), Laszlo Treszkai (generalized planning), Lewis Hammond (moral responsibility), and Michael Varley (Fairness).
