ELSA - Enhanced Latent SpAces for improved collider simulations

Introduction

This repo contains the code for the Enhanced Latent SpAces (ELSA) framework for neural network improved collider simulations. It is based on the LaSeR protocol [1] and further employs augmented flows [2]. The code is provided in PyTorch.
