Santaló Conference

The Faculty of Mathematical Science, in collaboration with the Journal Revista Matemática Complutense, created in 2002 the figure of Santaló Lecturer. Such a position is occupied each year by an invited distinguished professor (proposed by the Editorial Board of Journal and ratified by the Faculty Council) asked to submit an article to the Journal and give a colloquium lecture about it.

Title: Learning Algebraic Varieties from samples

Abstract:  This lecture addresses the role of algebraic geometry in data science. We discuss work with Paul Breiding, Sara Kalisnik and Madeline Weinstein, aimed at determining a real algebraic variety from a fixed finite subset of points. Existing methods are studied and new methods are developed. Our focus lies on topological and algebraic features, such as dimension and defining polynomials. All algorithms are tested on a range of datasets and made available in a software package in Julia.

Day: jueves 4 de octubre, 13:00.

Place: Aula Miguel de Guzmán, Facultad de Ciencias Matemáticas
