Fast calorimeter simulation
Tools and studies for fast simulation of calorimeter showers: detailed Geant4 / DD4hep simulation, compact point-cloud representations of the showers, and their use as input to machine-learning-based fast simulation. This organization hosts the trained weights; the code is on GitHub.
One photon shower as Geant4 steps and after two step2point compressions.
