We show recent developments on new methodologies for the determination of Parton Distribution Functions in the context of the NNPDF collaboration. We study different models and architectures in a systematic way which allows as to assess the quality of the fit: overtraining, model complexity, hyperparameter setup, optimization algorithm... We show a fully automatized pipeline to achieve a best model setup finding good improvements in both the quality and efficiency of the fits.
