<p>Hi, I am wondering what the difference between 'generalized gradient' and 'subgradient' of a (potentially non-differentiable) convex function 'f' is. </p> <p>The generalized gradient I am interested in is meant in the sense of the paper http://www.is.tuebingen.mpg.de/fileadmin/user_upload/files/publications/ICML2010-Kim_6519[0].pdf (see page 3, footnote 2).</p> <p>many thx for any help.</p>
