One World Seminar Series on the 

Mathematics of Machine Learning

The One World Seminar Series on the Mathematics of Machine Learning is an online platform for research seminars, workshops and seasonal schools in theoretical machine learning. The focus of the series lies on theoretical advances in machine learning and deep learning as a complement to the one world seminars on probability, on Information, Signals and Data (MINDS), on methods for arbitrary data sources (MADS), and on imaging and inverse problems (IMAGINE).

The series was started during the Covid-19 epidemic in 2020 to bring together researchers from all over the world for presentations and discussions in a virtual environment. It follows in the footsteps of other community projects under the One World Umbrella which originated around the same time.

We welcome suggestions for speakers concerning new and exciting developments and are committed to providing a platform also for junior researchers. We recognize the advantages that online seminars provide in terms of flexibility, and we are experimenting with different formats. Any feedback on different events is welcome.

Pruning Deep Neural Networks for Lottery Tickets 

Deep learning continues to impress us with breakthroughs across disciplines but comes at severe computational and memory costs that limit the global participation in the development of related technologies. Can we address some of these challenges by finding and training smaller models? The lottery ticket hypothesis has given us hope that this question might be answered by pruning randomly initialized neural networks. In this talk, we will prove a strong version of this hypothesis in realistic settings. Inspired by our theory, we will create a test environment that allows us to highlight current limitations of state-of-the-art algorithms in finding extremely sparse lottery tickets and highlight some opportunities for future progress.
