Convexity and Information ElicitationHow can we score a weather forecaster so she gives the most accurate predictions?
Glenn Brier's answer to this question in 1950 founded the field of elicitation: incentivizing strategic agents to reveal information.
The answers have deep connections to convexity, a fundamental feature that comes up all the time in machine learning and algorithms.
This series is based on my tutorial at EC '16 with Rafael Frongillo. You can see the slides from that tutorial at the above link.
