    Speaker:  Andreas Kyprianou, Bath Abstract: We analyse a class of fragmentation-coalescence processes defined on finite systems of particles organised into clusters. Coalescent events merge multiple clusters simultaneously to form a single larger cluster,  while fragmentation breaks up a cluster into a collection of singletons. Under mild conditions on the coalescence rates, we show that the distribution of cluster sizes becomes non-random in the...

    Speaker: Dr Ricardo Silva, Lecturer in Statistics, UCL Time: 3.30pm Abstract: In this exposition, we will discuss the common tools used in the machine learning community to describe causal assumptions and how this leads to particular ways of thinking concerning the estimation of causal effects. We will focus on two main case studies: how to combine data from observational and experimental studies; and how to criticise ways...

    Speaker:  Costanza Benassi, Department of Mathematics, Warwick Abstract:  Random loop models appear in a great variety of situations in both the probability and mathematical physics literature. Recently some striking conjectures have been suggested about the appearance of extended loops and the distribution of their lengths, which is expected to be a member of the Poisson Dirichlet distribution family.  We propose a general class of models for i...

    Time: 12.00 noon Abstract:  XTX Markets trades an average of $80B daily in thousands of financial instruments  on an electronic basis with  little human interaction. This adds liquidity to the global financial markets and is made possible by taking a highly systematic, purely data-driven, approach to trading.  In this talk, we will describe how trading can be automated, the sort of problems that it poses, and how a small team of mathematicians, ...

    Speaker: Geoff Nicholls, Department of Statistics, University of Oxford Title: The Savage Axioms for Dummies Abstract: In Bayesian inference the subjective expected utility is an object of foundational importance. The decision maker’s choices maximise this utility, and so it decides some elements of our statistical methodology. For the SEU to exist we need a prior and a utility representing the subjective beliefs of the analyst to exist. The Savage Axioms are a...

    Speaker: Raphael Forien, CMAP – École Polytechnique, France Title: Gene flow across geographical barriers Abstract: Barriers to gene flow are physical or biological obstacles which locally reduce migration and genetic exchanges between different regions of a species’ habitat. Genetic relatedness between individuals can be deduced from the distribution of the positions of their ancestors back in time. In the prese...
