### Convexity and Information Elicitation

How 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
