Call For Papers

Optimization is a cornerstone of nearly all modern machine learning (ML) and deep learning (DL). Simple first-order gradient-based methods dominate the field for convincing reasons: low computational cost, simplicity of implementation, and strong empirical results.

Yet second- or higher-order methods are rarely used in DL, despite also having many strengths: faster per-iteration convergence, frequent explicit regularization on step-size, and better parallelization than SGD. Additionally, many scientific fields use second-order optimization with great success.

A driving factor for this is the large difference in development effort. By the time higher-order methods were tractable for DL, first-order methods such as SGD and it’s main variants (SGD + Momentum, Adam, …) already had many years of maturity and mass adoption.

The purpose of this workshop is to address this gap, to create an environment where higher-order methods are fairly considered and compared against one-another, and to foster healthy discussion with the end goal of mainstream acceptance of higher-order methods in ML and DL.

Plenary Speakers:
- Amir Gholami (UC Berkeley)
- Coralia Cartis (University of Oxford)
- Frank E. Curtis (Lehigh University)
- Donald Goldfarb (Columbia University)
- Madeleine Udell (Stanford University)
