Zero-Order Optimization Methods with Applications to Reinforcement Learning
9/19/19 | 4:15pm | E51-335 Reception to follow. Jorge Nocedal Professor Northwestern University Abstract: We consider the problem of minimizing a noisy objective function using only function values. We first review the main approaches in the literature and then focus on two strategies that aim at estimating gradients. One is based on…

Managing Prediction Markets with Informed Agents
9/12/19 | 4:15pm | E51-335 Reception to follow. John Birge Professor The University of Chicago Abstract: Prediction markets can be used to extract the wisdom of the crowd, but an informed participant can manipulate such markets in many cases. This talk will describe how this can occur when participants or the…
