Stein’s method in machine learning [workshop]

There will be an ICML workshop on Stein’s method in machine learning & statistics, next July 14 or 15, located in Long Beach, CA. Organised by François-Xavier Briol (formerly Warwick), Lester Mckey, Chris Oates (formerly Warwick), Qiang Liu, and Larry Golstein. To quote from the webpage of the workshop

Stein’s method is a technique from probability theory for bounding the distance between probability measures using differential and difference operators. Although the method was initially designed as a technique for proving central limit theorems, it has recently caught the attention of the machine learning (ML) community and has been used for a variety of practical tasks. Recent applications include goodness-of-fit testing, generative modeling, global non-convex optimisation, variational inference, de novo sampling, constructing powerful control variates for Monte Carlo variance reduction, and measuring the quality of Markov chain Monte Carlo algorithms.

Speakers include Anima Anandkumar, Lawrence Carin, Louis Chen, Andrew Duncan, Arthur Gretton, and Susan Holmes. I am quite sorry to miss two workshops dedicated to Stein’s work in a row, the other one being at NUS, Singapore, around the Stein paradox.

California fires

“Imagine a leader who defies science, saying these solutions shouldn’t be part of his decision-making on our behalf. Imagine a leader who cares more for his own, convenient option than he does for the people he leads. Imagine an unfit leader. Now imagine a fit one.” Neil Young

Among the many fires that raged and rage throughout the West coast of both US and Canada this year the terrible one that took place in Paradise, near Chico, a few days ago was made much more personal by being the area where we had spent a week on holidays in Lassen National Park. While I think the place escaped the fire, it would be great to hear from the people who hosted us that they are safe… [The quote from Neil Young is related to another fire in Malibu.]

male masters

Yesterday, I received this wood plaque from the organisers of the San Francisco Marathon! Nice, as I had not expected them to deliver abroad. And with this surprising title of second place in the male masters. After checking on Google (and avoiding a long list of SM sites), it appears that this means the above 40 category, which I had never heard of before. (I would have preferred an above 50 category, obviously! Which appears to exist in some races as the Grand Master category, even better!) Looking further at some of the (running) links, it also appears that categories by weight have been introduced in some races… Not that I can expect to benefit from that further division!

winning entry at MCqMC’16

The nice logo of MCqMC 2016 was a collection of eight series of QMC dots on the unit (?) cube. The organisers set a competition to identify the principles behind those quasi-random sets and as I had no idea for most of them I entered very random sets unconnected with algorithmia, for which I got an honourable mention and a CD prize (if not the conference staff tee-shirt I was coveting!) Art Owen sent me back my entry, posted below and hopefully (or not!) readable.
