CMSA Combinatorics, Physics and Probability Seminar: Algebraic Statistics with a View towards Physics

April 26, 2022 9:00 am - 10:00 am
CMSA, 20 Garden St, G10
Address: 1 Oxford Street, Cambridge, MA 02138 USA
Speaker:

Bernd Sturmfels - MPI Leipzig and UC Berkeley


We discuss the algebraic geometry of maximum likelihood estimation from the perspective of scattering amplitudes in particle physics. A guiding examples the moduli space of n-pointed rational curves. The scattering potential plays the role of the log-likelihood function, and its critical points are solutions to rational function equations. Their number is an Euler characteristic. Soft limit degenerations are combined with certified numerical methods for concrete computations.


This seminar will be held in person and online via Zoom.
