Abstract
Following a ground-breaking proposal by Ji~\cite{PhysRevLett.110.262002}, numerical simulations of Quantum Chromo Dynamics (QCD) on a Euclidean lattice have provided new, valuable information on the structure of hadrons. In this talk, we briefly review the lattice approach to the reconstruction of parton densities, highlighting the connection between lattice observables and parton densities, with a focus on theoretical issues. Since parton distributions are extracted from lattice data by solving an inverse problem, we discuss some of the difficulties that affect these determinations and how they can be formulated in a Bayesian framework.

Reports on this Submission
Strengths
The contribution provides a nice status report on ongoing efforts to extract PDFs using as input lattice QCD data.
Weaknesses
No weaknesses
Report
The author summarises well the current status of extracting PDFs from lattice QCD data. I recommend publication
Requested changes
Two typos:
P. 4 second line from the bottom "need" --> "need to"
P.5 third line from Fig. 3 " a the light-cone"-->"the light-cone"
I recommend that the authors includes, apart from the lattice proceedings, the published work of Fig. 6.
