Event details
There is an interesting similarity between the way that neural networks learn about data and the way that models of particle production are structured. This connection between neural networks and renormalisable theories may help explain why deep learning has been successful for a wide range of tasks. In this talk I will describe a neural network that has been structured so as to behave as a toy parton shower model for particle production, which may make some of the connections between deep learning and particle physics more explicit. By applying a shower merging procedure, the network can be evaluated on unshowered events produced by a matrix element calculation. The trained network behaves as a parton shower that qualitatively reproduces jet-based observables.

About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
