Hi, welcome to HN. Your posted code was scrambled by the formatter (see https://news.ycombinator.com/formatdoc), so I cleaned it up and posted it at https://gist.github.com/rversteegen/460640b658217c1434633d3d...

It doesn't seem to work, the update rule seems wrong, but I'll look tomorrow. (Still reading the paper). Thanks for that, debugging a piece of code is educational!
