With the rapid advance in machine learning in the recent years, the idea of enabling intelligent agents to communicate with each other and with humans is turning from a hot topic for philosophical debates into a practical engineering problem. Learning to communicate through interactions, rather than relying on explicit supervision, is often considered as a prerequisite for developing a general AI. I am going to present our recent work (https://openreview.net/pdf?id=SkaxnKEYg) that has been accepted to ICLR2017 workshop. If you are curious about how to efficiently teach agents to communicate with each other, you are welcome to attend my talk.
