Training codes for various problems solved with machine learning.
WAWTPC - regression task. Reconstruct 3D positions of track endpoints from three 2D projections: U, V, W. The projections share a common axis: Z, but the other exes are not orthogonal.
TauTauMass - regression problem. Reconstruct the full tau-tau system invariant mass, having the data as from High Energy Physics (HEP) detector: four momenta of all particles except for neutrinos. For neutrinos we have only the vectorial sum of momenta in a given plane.
