Neural Network Field Theories: Non-Gaussianity, Actions, and Locality

no code implementations6 Jul 2023 Mehmet Demirtas, James Halverson, Anindita Maiti, Matthew D. Schwartz, Keegan Stoner

Conversely, the correspondence allows one to engineer architectures realizing a given field theory by representing action deformations as deformations of neural network parameter densities.

Simplifying Polylogarithms with Machine Learning

no code implementations8 Jun 2022 Aurélien Dersy, Matthew D. Schwartz, Xiaoyuan Zhang

Polylogrithmic functions, such as the logarithm or dilogarithm, satisfy a number of algebraic identities.

Challenges for Unsupervised Anomaly Detection in Particle Physics

no code implementations13 Oct 2021 Katherine Fraser, Samuel Homiller, Rashmish K. Mishra, Bryan Ostdiek, Matthew D. Schwartz

We then show that optimal transport distances to representative events in the background dataset can be used directly for anomaly detection, with performance comparable to the autoencoders.

JUNIPR: a Framework for Unsupervised Machine Learning in Particle Physics

no code implementations25 Apr 2018 Anders Andreassen, Ilya Feige, Christopher Frye, Matthew D. Schwartz

As a third application, JUNIPR models can reweight events from one (e. g. simulated) data set to agree with distributions from another (e. g. experimental) data set.
