We motivate the study of the uncertainties of the parton distributions in view of precision physics at the LHC. After reviewing the standard techniques, we introduce the neural network approach to global fits of parton distribution functions. First we review previous work on unbiased parametrizations of deep-inelastic structure functions with faithful estimation of their uncertainties, and then we summarize the current status of neural network parton distribution fits.
