Talk Particle Physics Applications in Particle Physics

Speaker

Lukas Alexander Heinrich (CERN)

Description

One of the key difficulties in making HEP differentiable is the highly stochastic and discrete nature of both simulation and reconstruction. While not directly differentiable, gradients of expectation values of stochastic simulator output can be estimated using probabilistic programming and score functions. In this talk I will demonstrate score function based optimization of material maps on a toy particle shower example and discuss possible future directions.
