The campus extends about 1 mile 1. These are in turn surrounded by a ring of athletic facilities, smaller administration buildings, and parking lots. The award refers to its innovative design, efficiency, reliability, system redundancy, and environmental benefits. The award states it was given "In recognition of exemplary public leadership in advancing energy efficiency and global environmental stewardship through investment in an innovative district energy system.
Research Interests My research interests center on learning in machines and animals. I have been working on developing learning algorithms that are useful for engineering applications but that also make contact with learning as studied by psychologists and neuroscientists.
Although I make no claims to being either a psychologist or a neuroscientist, I spend a lot of my time interacting with psychologists and neuroscientists and reading literature in those fields.
I feel strongly that new developments should be integrated as closely as possible with the state-of-the art in as many of the relevant fields as possible. It is also essential to understand how new developments relate to what others have done in the past.
In the case of reinforcement learningwhose main ideas go back a very long wayit has been immensely gratifying to participate in establishing new links between reinforcement learning and methods from the theory of stochastic optimal control. Especially exciting to me are the connections between temporal difference TD algorithms and the brain's dopamine system.
These are partly responsible for rekindling my interest in reinforcement learning as an approach to building and understanding autonomous agents, rather than as a collection of methods for approximating solutions to large-scale engineering problems.
Though my interest in the latter is still strong! Most of my recent work has been about extending reinforcement learning methods so that they can work in real-time with real experience, rather than solely with simulated experience as in many of the most impressive applications to date.
Of particular interest to me at present is what psychologists call intrinsically motivated behavior, meaning behavior that is done for its own sake rather than as a step toward solving a specific problem of clear practical value.
What we learn during intrinsically motivated behavior is essential for our development as competent autonomous entities able to efficiently solve a wide range of practical problems as they arise.
Recent work by my colleagues and me on what we call intrinsically motivated reinforcement learning is aimed at allowing artificial agents to construct and extend hierarchies of reusable skills that form the building blocks for open-ended learning.
