Event details

Abstract: This talk will address the problem of quantifying the expected value of some function of a random variable with unknown distribution. Typical problems of this type include determining the expected profit of a stock portfolio with uncertain returns and quantifying the symbol error rate in a noisy communication channel. In particular, the talk will address cases in which only limited or ambiguous moment information is available, but some additional structural properties – e.g. symmetry, unimodality or monotonicity – are known to hold. In such cases, one can compute a sharp upper bound on the worst-case expectation, taken over all distributions satisfying the partial moment and other structural information available. The results can also be applied to control of linear systems with chance constraints, for which robust conditional Value-at-Risk (CVaR) conditions can be used to control both the probability and the degree of constraint violations.
