I am a Research Scientist in DeepMind's Edmonton office. Lately, I've been working on multiagent RL and environments shared by humans and agents using virtual reality. My most recent paper is on the emergence of microeconomic behaviour in populations of RL agents, in an environment where they learn to produce, consume, and exchange goods. The agents are generic RL agents used in other environments, and learn this behaviour from scratch, with no domain knowledge coded into the agents: they learn this behaviour on their own, through trial and error.In ways familiar to any Microeconomics 101 student, we can study the effects of supply or demand shifts, and we find that the agents often respond in the ways we predict: if one resource is made more rare in the environment, then the agents converge to a higher price. If we cause an increase in the price of a good, then agents respond by trying to produce more of it, and consume less of it.
