FLAG’s research lies primarily in the development and application of reinforcement learning (RL) algorithms. These algorithms allow intelligent software agents to learn to carry out near-optimal decision making in the context of sequential decision-making tasks, based on a reward signal. RL methods can learn to perform at high levels even on tasks where human knowledge is limited.

Our current research is focused on three main areas:

  • The extension of RL methods to problems with multiple conflicting objectives. We have been among the world leaders in establishing multiobjective reinforcement learning (MORL) as a distinct and growing sub-discipline of RL.
  • Development and evaluation of methods to implement safe, trusted, explainable and ethical autonomous artificial intelligence, generally within the MORL framework.
  • Development of assisted RL methods which can learn effectively both when provided with advice by a human or other advisor, or when learning independently.

Our work sometimes crosses over into related areas such as broader machine learning, and specific areas of application including cybersecurity and digital forensics.
