What is it about?
In laboratory astrophysics experiments involving plasma, scientists commonly use ion imaging to observe electromagnetic fields. However, it remains challenging to deduce these fields solely from the images. To address this, we propose employing machine learning techniques. By training computers with various examples from theory or numerical simulations, we aim to teach them how to reconstruct the fields from the images.

Why is it important?
This paper represents an initial exploration, showcasing the feasibility of our proposed idea through simplified systems. Our results highlight the efficacy of employing neural networks, with a notable correlation between predicted and actual values.
Perspectives
While some scientists view machine learning as a mysterious 'black box' lacking explanatory power compared to scientific theories, we've discovered that incorporating physics knowledge during the computer's training can significantly enhance its performance.
