Eindhoven Stochastics Seminar

Oct 5, 2018, 12:45 - 13:30
MF 11-12 (4th floor MetaForum Building, TU/e)

Andreas Kyprianou (University of Bath) Some strange results in fragmentation-coalescence models 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 large-scale limit. Moreover, we discover that, in the limit of small…

Joris Mulder (Tilburg University) The Matrix-F Prior for Estimating and Testing Covariance Matrices The matrix-F distribution is presented as prior for covariance matrices as an alternative to the conjugate inverted Wishart distribution. A special case of the univariate F distribution for a variance parameter is equivalent to a half-t distribution for a standard deviation, which is becoming increasingly popular in the Bayesian literature. The matrix-F distribution can be conveniently modeled as a Wishart mixture of Wishart or inverse Wishart distributions,…

Sponsored by Summary Global warming, climate agreements, EU policies to reduce CO2 emissions and many national energy programs reflect the need to make our energy systems more sustainable. This process, called energy transition, entails a fundamental change of the energy system from a centralized system with electricity production mainly based on fossil fuels to a decentralized local system based on sustainable energy production based on e.g. solar, wind, tidal, hydro or geothermal sources. Other changes include the ongoing growth of…

Ziv Scully (Carnegie Mellon University)  SOAP: One Clean Analysis of All Age-Based Scheduling Policies We consider an extremely broad class of M/G/1 scheduling policies called SOAP: Schedule Ordered by Age-based Priority. The SOAP policies include almost all scheduling policies in the literature as well as an infinite number of variants which have never been analyzed, or maybe not even conceived. SOAP policies range from classic policies, like first-come, first-serve (FCFS), foreground-background (FB), class-based priority, and shortest remaining processing time (SRPT);…

Eindhoven Stochastics Colloquium

Stefan Klootwijk (University of Twente) On Random Shortest Path Metrics Simple heuristics often show a remarkable performance in practice for optimization problems. Worst-case analysis often falls short of explaining this performance. Because of this, "beyond worst-case analysis" of algorithms has recently gained a lot of attention, including probabilistic analysis of algorithms. The instances of many optimization problems are essentially a discrete metric space. Probabilistic analysis for such metric optimization problems has nevertheless mostly been conducted on instances drawn from Euclidean…

20th Anniversary Eurandom

Dec 17, 2018 - Dec 19, 2018
MF 11-12 (4th floor MetaForum Building, TU/e)

Summary This year Eurandom is celebrating it's twentieth anniversary!! Hard to believe it is already so long ago that the new European Unit for Research and Analysis of Non-Deterministic Operational Models was established in Eindhoven, on the campus of the Eindhoven University of Technology. Many postdocs and PhD students have come to Eurandom to start and develop their careers. Friendships were formed, serious work and research were alternated with fun and social events. There has always been a very good atmosphere in the office and among…

Eindhoven Stochastic Colloquium

Jan 17, 15:00 - 16:00
MF 11-12 (4th floor MetaForum Building, TU/e)

Jeannette Janssen (Dalhousie University) Recognizing graphs formed by a spatial random process It is a safe assumption about social networks that links are more often formed between people that have a lot in common. This can be modelled with a simple spatial model for link formation. Individuals are represented by vertices placed in a virtual space that represents their interests and characteristics. Links are formed stochastically so that most links are local, i.e. links are less likely between vertices that…

Sam Thomas (Cambridge University) Cutoff for Random Walk on Dynamical Erdos-Renyi  We study the behaviour of random walk on dynamical percolation. In this model, the edges of a graph are either open or closed and refresh their status at rate μ, while at the same time a random walker moves on G at rate 1, but only along edges which are open. In this talk I shall present recent results proving cutoff in the case when G is the complete…
