Optimization in the Presence of Noise

Figen Öztoprak

Abstract:

We consider optimization problems with noisy objective and/or constraint functions. Such problems arise in a variety of applications including machine learning. We present a few examples with different sources and models of noise. As solution methods, we focus on extensions of gradient-based algorithms (such as gradient descent and sequential quadratic programming) that employ approximate derivatives. We discuss the effect of the noise in function and derivative evaluations on the solution processes and convergence results of those algorithms. Throughout the talk, we provide a brief overview of relevant recent research and open questions.
