An Overview of Machine Teaching
This is an incremental contribution that provides a conceptual framework for researchers in machine teaching.
The paper organizes machine teaching concepts into a dimensional framework to characterize existing teaching problems, aiming to provide deeper understanding, reveal connections, and identify research gaps in the field.
In this paper we try to organize machine teaching as a coherent set of ideas. Each idea is presented as varying along a dimension. The collection of dimensions then form the problem space of machine teaching, such that existing teaching problems can be characterized in this space. We hope this organization allows us to gain deeper understanding of individual teaching problems, discover connections among them, and identify gaps in the field.
