Renowned mathematician Alessio Figalli, winner of the Fields Medal in 2018, delves into the world of optimal transport – the art of efficiently moving resources from one point to another. Understanding this concept is crucial in various fields, from meteorology to machine learning.
Figalli values mathematics for its concrete applications and timeless truths. He believes that math, unlike other disciplines, offers certainty: theorems are either true or false, enduring the test of time. He views math as a language to describe nature and a creative process to model the world we observe.
The study of optimal transport traces back to Gaspard Monge, a French mathematician, and has since evolved to encompass diverse applications, from military engineering to logistics. Figalli highlights Leonid Kantorovich’s work on resource allocation, emphasizing the importance of optimizing global utility rather than prioritizing individual gains.
In the realm of machine learning, Figalli is exploring ways to combat the curse of dimensionality through advanced optimal transport techniques. By collapsing dimensions and reconstructing data from lower-dimensional spaces, he aims to enhance the reliability and robustness of machine learning algorithms.
Figalli’s work bridges the gap between pure and applied mathematics, demonstrating the practical significance of theoretical advancements. By leveraging mathematical principles to address real-world challenges, he seeks to unlock new possibilities in machine learning and optimize the potential of artificial intelligence.
