Description

The application of deep learning techniques using convolutional neu-
ral networks to the classification of particle collisions in High Energy Physics is
explored. An intuitive approach to transform physical variables, like momenta of
particles and jets, into a single image that captures the relevant information, is
proposed. The idea is tested using a well known deep learning framework on a sim-
ulation dataset, including leptonic ttbar events and the corresponding background
at 7 TeV from the CMS experiment at LHC, available as Open Data. This initial
test shows competitive results when compared to more classical approaches, like
those using feedforward neural networks.
