www.numerical-tours.com/2016/09/17/python-tours/New Python Tours<p><a href="https://www.gipsa-lab.grenoble-inp.fr/~laurent.condat/">Laurent Condat</a> just released a very nice set of <a href="http://www.numerical-tours.com/python/">Python tours</a> on optimization and applications in imaging. Simply go to the <a href="http://www.numerical-tours.com/python/">“optimization” section</a> in the Python’s tours. These new tours cover a wide range of topics, but target in particuler non-smooth convex optimization and first order proximal splitting schemes. Thanks <a href="https://www.gipsa-lab.grenoble-inp.fr/~laurent.condat/">Laurent</a>!</p>

www.numerical-tours.com/2016/06/14/python-optimization/Updated tour<p>I have updated the tour on <a href="/matlab/optimaltransp_5_entropic/">Entropic Regularization of Optimal Transport</a>. It now present the algorihtms the way they should be presented, i.e. using the concept of diagonal scaling, that corresponds to Sinkhorn’s algorithm in the case of transport, and that can be extended to the computation of barycenters.</p>

This means in particular that Matlab tours now run natively with the use of the <a href="https://github.com/calysto/matlab_kernel">Matlab kernel</a>.</p>

It relies on the powerful result that the level sets of the heat diffusion converge to those of the geodesic distance as the diffusion time tends to 0.</p>
