IML workshop challenge on jet mass regression

This dataset is associated with the LPCC IML (Lhc Physics Center at Cern Inter-experimental Machine Learning) working group. It was produced for the second IML annual workshop (April 2018). This dataset is part of a machine learning "challenge" on jet mass regression at future circular collider (FCC) conditions.
