This course provides a thorough introduction and overview of reinforcement learning. Reinforcement learning algorithms repeatedly answer the question "What should be done next?", and they can learn via trial-and-error to answer these questions even when there is no supervisor telling the algorithm what the correct answer would have been. Applications of reinforcement learning span across medicine (How much insulin should be injected next? What drug should be given next?), marketing (What ad should be shown next?), robotics (How much power should be given to the motor?), game playing (What move should be made next?), environmental applications (Which countermeasure for an invasive species should be deployed next?), and dialogue systems (What type of sentence should be spoken next?), among many others. Broad topics covered in this course will include: Markov decision processes, reinforcement learning algorithms (model-based/model-free, batch/online, value function-based, actor-critics, policy gradient methods, etc.), and representations for reinforcement learning. Special topics may include ensuring the safety of reinforcement learning algorithms, hierarchical reinforcement learning, theoretical reinforcement learning, multi-agent reinforcement learning, and connections to animal learning. This course assumes a very strong mathematical background in calculus, linear algebra, and strategies for proving theorems. We will emphasize hands-on experience in class and through assignments, which will require implementing and applying many of the algorithms we discuss. Therefore, a strong background in programming is also necessary, as we will require that students implement sophisticated learning algorithms using C++ and/or Python. Finally, we assume that students have a background in machine learning (COMPSCI 589 or 689) and artificial intelligence (COMPSCI 683). 3 credits.
