CHEMISTRY: Catalysts Taking Turns

Taking turns in general sum Markov games

This paper provides a novel approach to multi-agent coordination in general sum Markov games. Contrary to what is common in multi-agent learning, our approach does not focus on reaching a particular equilibrium between agent policies. Instead, it learns a basis set of special joint agent policies, over which it can randomize to build different solutions. The main idea is to tackle a Markov game...

Taking Turns in Flying with a Virtual Wingman

In this study we investigate how human pilots interact with a virtual wingman, represented by our virtual agent Ashley. Based on recordings of an earlier experiment, we made an inventory of the type of problems that occur in such interactions. In an effort to derive what type of cues elicited by the human pilots could provide indicators to Ashley to recognize such problems by herself, we design...

Taking Turns and Talking Ties: Networks and Conversational Interaction

Conversational encounters are permeable to network effects but not entirely so, for conversation is internally structured by sequential constraints and dependencies that limit the latitude people have to act on their relational commitments. The author analyzes the effects of hierarchical (superior-subordinate) and horizontal (friendship and co-working) networks on “participation shifts”—transit...

Future of Chemistry Assumptions: Taking Chemistry in New Directions**

Speculating about the future of science seems to be genetically encoded in scientists. We all do it. We also take it as an article of faith that serious predictions are almost always wrong. Is thinking about the future an important thing to do, or just a diversion—like daydreaming, or gardening, or playing the lottery? Why do we spend our time guessing about matters we believe we cannot predict...
