We present Hit-reco model for denoising and region of interest selection on raw simulation data from ProtoDUNE experiment. ProtoDUNE detector is hosted by CERN and it aims to test and calibrate technologies for DUNE, a forthcoming experiment in neutrino physics. Hit-reco leverages deep learning algorithms to make a first step in the reconstruction workchain, that consists in converting digital detector signals into physical high level quantities. We benchmark the artificial intelligence based approach against traditional algorithms implemented by the DUNE collaboration. We investigate the capability of graph convolutional neural networks, while exploiting the IBM Minsky multi-GPU setup to accelerate training and inference processes.
