Hierarchical Anticipatory Learning (HAL Lab)

The brain is an amazing adaptive system able to make sense of the world and guide flexible behavior. We study how such a system learns from experience and guides decision-making. Besides modeling specific brain processes in conjunction with physiological and behavioral studies, we apply such cognitive processes to robots.

While we are specifically interested in biological information processing, the field of machine learning and computational neuroscience has become the forefront in application development at Google and Microsoft. It can also be applied to advanced data mining and artificial intelligence.
