Princeton Day of Optimization

Join us for the first edition of the Princeton Day of Optimization, organized by the Department of Operations Research and Financial Engineering (ORFE) at Princeton University. Register here.

Theme

For its inaugural edition, the Princeton Day of Optimization will gather researchers whose work is at the intersection of optimization, control, and machine learning. The workshop aims to investigate the creative symbioses that arise when researchers consider problems at the interface between two (or all) of these areas.

A note from the organizer

In the past and now still, optimization has been the key tool that underlies many problems in both machine learning and control. In machine learning, the technology behind the training of most modern classifiers relies in a fundamental way on optimization. In control, recent advances in nonconvex optimization are leading to a paradigm shift from classical linear control to a principled framework for design of nonlinear controllers that are provably safer, more agile, and more robust.

Nowadays we also observe an inverse phenomenon where ideas from control and learning lead to fascinating new research within the optimization community. For example, the focus of the learning community on scalable and computationally tractable methods has forced optimizers to develop new variants of classical algorithms that are able to keep pace with the vast quantities of data at hand. Optimizers are also thinking harder about notions of optimality that better incorporate robustness as, in many problems in learning, over-optimizing a model on training data leads to poor generalization on test data. In addition, a bevy of interesting theoretical questions in optimization have come out of the success of popular heuristics used in the learning community (e.g., for training of neural networks) and are yet to be answered. In a similar way, fundamental ideas in control theory have led to new algorithmic developments within optimization. For example, a new research direction has emerged that interprets a multitude of optimization algorithms as dynamical systems and uses tools from robust control to improve their convergence rate analyses. Finally, there is exciting new activity at the juncture between machine learning and control. In particular, the problem of learning the parameters of a dynamical system on the fly, while simultaneously controlling it, has received much renewed attention. Advances in this direction are important for various applications in robotics and cyber-physical systems, among other areas of high impact.

The goal of the first edition of the Princeton Day of Optimization is to inspire new research directions at the interface of optimization, control, and machine learning, such as the ones mentioned above. To this effect, we have reached out to prominent researchers whose work straddles at least two of the three areas.

We are excited to hear what these wonderful speakers have to say, and we very much hope to see you all there!
