The Artificial Intelligence and Machine Learning group (AI-ML) at Universitat Pompeu Fabra, Barcelona, Spain, is looking for postdoctoral researchers in the area of reinforcement learning. The AI-ML group mainly focuses on fundamental research, developing novel algorithms and proving properties about these algorithms. The research will take place in the context of a Spanish project on continual (or lifelong) learning and planning, with a focus on decision strategies that generalize to a range of tasks, hierarchical representations for reinforcement learning, and potentially multiagent learning.
