There&#x27;s a bunch of phrasing that makes me want to give it the stinkeye, but nothing horrible.  This isn&#x27;t my field, but from part 1 it looks like he&#x27;s trying to replace a Gaussian distribution by a Laplacian one and exploit some kind of underlying symmetry, but that doesn&#x27;t really mesh with his &quot;conclusions&quot; in part 5.
