Reviews: Teaching Multiple Concepts to a Forgetful Learner

Originality: The work is a nice combination of developments in a few fields -- applying analysis and concepts from machine teaching to concept learning in forgetful humans. To the best of my knowledge, the theoretical analysis is novel. However, they missed some critical work in the field and missed an opportunity to compare their method to very relevant pre-existing work. This includes the following references: 1) Patil, Zhu, Kopec, & Love (2011). It is similar and may even be isomorphic to the case in this submission (I doubt it's isomorphic).
