How do I use this calendar?

You can click on an event to display further information about it.

The toolbar above the calendar has buttons to view different events. Use the left and right arrow icons to view events in the past and future. The button inbetween returns you to today's view. The button to the right of this shows a mini-calendar to let you quickly jump to any date.

The dropdown box on the right allows you to see a different view of the calendar, such as an agenda or a termly view.

If this calendar has tags, you can use the labelled checkboxes at the top of the page to select just the tags you wish to view, and then click "Show selected". The calendar will be redisplayed with just the events related to these tags, making it easier to find what you're looking for.

Title: What does non-reversibility really buy you in MCMC, with application to parallel tempering.

Abstract: In this talk I will review the popular “lifting” mechanism for producing non-reversible Markov chain Monte Carlo such as non-reversible Metropolis-Hastings and piecewise-deterministic Markov processes. These methods aim to have better mixing by providing momentum to break down random walk behaviour of algorithms. The presentation will investigate how these behave in a collection of stylised high-dimensional examples showing that the non-reversibility can often be washed out by the problem complexity so that the algorithm behaves asymptotically in a reversible way. On the other hand lifted algorithms still retain a small efficiency advantage over their reversible counterparts.
