Using AI to Model Laser Fusion Implosions | Machine Learning for Fusion

How can artificial intelligence be used to simulate implosions in laser fusion, where capsules of fuel are compressed to create miniature man-made stars? Laser fusion is a method of confining a fusion plasma where high power lasers are used to compress capsules of fuel to the width of a human hair, and heat them to temperatures comparable to the sun. In this video we describe the process of surrogate modelling, where a machine learnt model is used as a cheap and actionable version of expensive simulations. One way to build surrogate models is through neural networks, though these methods often need vast amounts of data to perform effectively. In a recent study from the OMEGA laser fusion facility in the United States, scientists used a method known as transfer learning to train machine learning surrogate models: first on many low fidelity simulations, then on high fidelity simulations and experiments. This transfer learning approach (an example of the broader method of multi fidelity machine learning) has led to the development of effective surrogate models in laser fusion. These models can be used to optimise laser fusion experiments and improve simulations, bringing us one step closer to fusion energy. ———————————————————————— 📌 Timestamps ———————————————————————— 00:00 - Intro & recap 01:28 - Laser fusion 02:11 - Radiation hydrodynamics 03:03 - Surrogate modelling 03:42 - Neural networks 04:51 - Deep learning 05:16 - Training models on experiments 06:21 - Transfer learning 07:02 - OMEGA laser transfer learning 07:40 - Study results 08:23 - Surrogates to optimise laser fusion 09:52 - Improving simulations with ML 10:59 - Conclusions ———————————————————————— 📚 Resources ———————————————————————— The paper discussed in this video can be accessed here: https://ieeexplore.ieee.org/abstract/... ———————————————————————— Connect with us ———————————————————————— Website - https://www.digilab.co.uk/ LinkedIn:   / cyd-cowley-2846a7125     / digilab-solutions-ltd   X: https://x.com/digiLab_ai ———————————————————————— 🎵 Music ———————————————————————— Achievement by Alex-Productions | https://onsound.eu/ Music promoted by https://www.free-stock-music.com Creative Commons / Attribution 3.0 Unported License (CC BY 3.0) https://creativecommons.org/licenses/... ———————————————————————— 🏷️ Tags ———————————————————————— Fusion Energy Tech Machine Learning Artificial Intelligence ———————————————————————— ✨ Hashtags ———————————————————————— [#AI] (https://www.youtube.com/hashtag/AI) [#fusion] (https://www.youtube.com/hashtag/fusion) [#energy] (https://www.youtube.com/hashtag/energy) [#physics] (https://www.youtube.com/hashtag/physics) [#science] (https://www.youtube.com/hashtag/science) [#megaprojects] (https://www.youtube.com/hashtag/megap...)
