the huge amount

of data

the high dimension-

the complexity

of phenomena

Finding relevant cases in this data deluge

can potentially revolutionize physics!

But we need to find the needle in the haystack.

### We develop new machine learning methods

for better science in High Energy Physics and Solar Physics.

**RODEM in a nutshell**

RODEM is a SNSF/SINERGIA project fostering cooperation between high energy physicists, solar physicists and experts in machine learning in Switzerland to advance research methodologies in both fields.

During the last decade, the amount of data available to scientists has increased enormously. New infrastructures, such as the Large Hadron Collider (LHC), and a new generation of solar observatories, such as the Solar Dynamics Observatory (SDO), produce data on a scale that cannot be exploited to their full extent with existing methods.

Simultaneously, data science has experienced real game changing breakthroughs in the past years. In particular, deep learning methods have shown the potential of data driven approaches compared to traditional algorithmic approaches. The following questions will shape research stragegies.

#### ➤ Can data driven methods support us in unraveling new physics?

#### ➤ Can physics support us in making better deep learning models?

Now is the time to unite our experience in both physics and machine learning to deeply dive into the many challenges of this combination. The rewards will undoubtedly bring both domains forward, resulting in better forecasting tools, generative models and anomaly detectors to be applied in the fields of High Energy Physics and Solar Physics.
