MLHEP 2020 Calorimeter regression

This challenge is aimed to recover the particle initial position and momentum in LHCb calorimeter. 

The calorimeter system is designed to stop particles as they pass through the detector, measuring the amount of energy lost as each one grinds to a halt. Two types of calorimeter are used at LHCb.
The electromagnetic calorimeter is responsible for measuring the energy of lighter particles, such as electrons and photons, while the experiment's hadron calorimeter samples the energy of protons, neutrons and other particles containing quarks.

MLHEP 2020 Calorimeter regression: Evaluation

The submission will be evaluated using scoring function from this code gist.

MLHEP 2020 Calorimeter regression: Rules

Zipped results must be submitted before the 2020-07-24 23:00:00+00:00.

Zipped file should contain a single npz-file named data_test_prediction.npzThis npz-file should contain two numpy arrays in it: ParticlePoint and ParticleMomentum. You may submit 15 submissions every day and 200 in total.

Also, please, if you are submitting not code solution, but raw predictions, please, add a link to where we can find your code in a comment to submission.
