Happy to announce I passed my viva for my thesis "Dimensionless Bayesian Model-Based Reinforcement Learning" I thank the examiners Dr Christos Anagnostopoulos and Prof Carl Edward Rasmussen for their comments and insightful discussions.

Some teaser before the thesis is published: 2 RL agents trying to solve the cartpole problem with a shifted pole length. Both are trained in the same single environment (with length of 1 meter) but only the one trained in a dimensionless MDP (right fig) transfers succesfully.

This is the dream team (plus some online that couldn't make it) that made the first ever @MLinScience conference happen. Huge thanks to speakers and poster presenters for presenting their work and the sponsors that helped fund it!

👀 Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse: nasa.gov/webbfirstimage…

An important intuition about Stochastic Gradient Descent (SGD) is that when you are far from the solutions, individual stochastic gradients will more or less point in the same direction, but at optimum, since their average is 0, they will all point in different directions !

Great to see the work out at last @gw_hunter ! Well done to Francesco Tonoloni, @CMessengerGW, & Ik Siong Heng! A great collaboration between CS & Physics! @IDAglasgow @GlasgowCS @UofGPhysAstro @QuantIC_QTHub
Dr. Hunter Gabbard@gw_hunter

I'm beyond excited to announce work which was a large part of my thesis has now been published in @NaturePhysics! We show for the first time that a form of #ML can provide estimates on #GW parameters in a fraction of the time of traditional methods. nature.com/articles/s4156…
