(Large) Language Models as an Example of Machine Learning / Artificial Intelligence — in English
Přednášející: Mgr. Rudolf Rosa, Ph.D., ÚFAL MFF UK
Anotace:
The talk will explain what (large) language models are and how they work, including notes on the current development and challenges in the field. Language models will be used as an example of employing machine learning / artificial intelligence approaches, leading to a more general explanation of what machine learning is, how it works, how it can be used, and what are its strengths and weaknesses. Depending on the remaining time, we may then look at some contemporary examples of successful applications of artificial intelligence approaches in the context of various fields.

The key role of turbulence in space plasmas
Přednášející: Dr. Luca Franci, Royal Society University Research Fellow, Imperial College London, London, UK
Anotace:
I will discuss the development and properties of turbulence and its importance for
energy dissipation and the particle dynamics in the solar wind. I will show MHD, hybrid, and fully
kinetic simulations which model the turbulent energy cascade from large fluid scales down to
electron scales. These recover a remarkable agreement with spacecraft measurements in the
solar wind and in the Earth’s magnetosheath, uncovering efficient mechanisms for energy
dissipation and particle energization in collisionless plasmas. Turbulence is observed to drive
magnetic reconnection, which then converts electromagnetic energy into particle energy. Also,
turbulent structures trap and energize particles. I will show how my simulations motivated a new
analysis of Solar Orbiter’s observations of compressive fluctuations in the slow solar wind.
Finally, I will present my research plan to tackle the particle dynamics in space plasmas by
combining innovative 3D models and observations by space missions.
