Much of the research in machine learning has focused on designing algorithms for discovering knowledge from data and learning a target model. What if there is a ``teacher" who knows the target already, and wants to steer the ``learner" towards this target as quickly as possible?  For instance, in an educational setting, the teacher (e.g., a tutoring system) has an educational goal that she wants to communicate to a student via a set of demonstrations and lessons; in adversarial attacks known as training-set poisoning, the teacher (e.g., a hacking algorithm) manipulates the behavior of a machine learning system by maliciously modifying the training data. This lecture will provide an overview of machine teaching and cover the following three aspects: (i) how machine teaching differs from machine learning, (ii) highlight the problem space of machine teaching across different dimensions, and (iii) discuss our recent work on developing teaching algorithms for human learners.
