Self-learning machines hunt for explosions in the universe

The National Science Agenda has awarded a 5 million euro grant to CORTEX – the Center for Optimal, Real-Time Machine Studies of the Explosive Universe. The CORTEX consortium of 12 partners from academia, industry and society will make self-learning machines faster, to figure out how massive cosmic explosions work.
In CORTEX maken we kunstmatige intelligentie beter en sneller, om samensmeltende sterren beter te bestuderen, en om toepassingen mogelijk te maken in maatschappij en bedrijfsleven.

Machine learning has rapidly become an integral part of our lives. It is now commonly used for speech recognition and information retrieval. This is also true in science, for detecting patterns in nature and the Universe. But the need is growing rapidly for such machines to respond quickly, for example in self-driving cars and for responsive manufacturing. On a more fundamental level, self-learning machines help us unveil a dynamical Universe we did not know existed up until recently. Bright explosions appear all over the radio and gravitational-wave sky. Many citizens and scientists are curious to understand where these come from.

“In CORTEX we aim to solve these open problems by bridging fundamental research to society,“ says Dr. Joeri van Leeuwen (ASTRON), the project lead. “We can only reach these ambitious goals if academic, applied, public and industry partners work together.”

Radio afterglow

The 5 million Euro grant from the Nationale Wetenschapsagenda: Onderzoek op Routes door Consortia (NWA-ORC) program will thus fund research at partners ASTRON, Nikhef, SURF, Netherlands eScience Center, Universiteit van Amsterdam, Radboud Universiteit Nijmegen, Centrum Wiskunde & Informatica, IBM Nederland B.V., BrainCreators B.V., ABN AMRO N.V., NVIDIA, NOVA, and Stichting ILT; in cooperation with Rijksmuseum, Thermo Fisher Scientific, and Leiden University.

“Gravitational waves whipped up by merging black holes and neutron stars peak for less than a few seconds, maybe several times per month,” says Dr. Sarah Caudill (Nikhef), “and fast self-learning machines can help us recognize the events as they occur.” Responding quickly to these using radio telescopes can help us understand better how the universe works, Dr. Antonia Rowlinson (University of Amsterdam and ASTRON) explains: “Using machine learning, we will pick out their radio afterglow from thousands of sources and, by watching how they change, we can determine the vast energies that must be involved”.

Faster and better

“CORTEX is unique in that we subsequently translate the latest mathematical and computer-science discoveries in faster and better computing for industry and society,“ says Dr. Raymond Oonk from SURF. Maarten Stol from BrainCreators B.V. concurs: “Both for startups and for large companies, machine learning on large data streams is essential. Only in a collaboration such as CORTEX can cutting edge science make its way to innovation in business.”
