TitleAssessment and visualization of the plant diversity – multi-functionality relationship AbstractIrish intensive grasslands are threatened by fluctuations in fertilizer prices and … Read more

On April 6th, the seminar series welcomed Prof. Anna Vidotto from the University of Naples Federico II to present recent work completed with Domenico Marinucci and Maurizia Rossi. TitleOn the excursion area of time dependent spherical random fields AbstractIn this paper, we consider isotropic and stationary real Gaussian random fields defined on S2×R and we investigate … Read more

On March 16th, Daniel hosted a reading group session on the seminal work by Sir David Cox, Regression Models and Life-Tables. The paper is available here.

On March 9th, the seminar series was delighted to welcome Prof. Nicos Pavlidis, Senior Lecturer at Lancaster University to speak about new work developing spectral subspace clustering methods with extensions to constrained clustering and active learning. Abstract: Spectral-based subspace clustering methods have proved successful in many challenging applications such as gene sequencing, image recognition, and motion segmentation. … Read more

On February 16th, the seminar series was delighted to welcome Prof. Alessandro Casa of the Free University of Bozen-Bolzano to speak about new work developing co-clustering methods for time-dependent data. Abstract: Multivariate time-dependent data arise when multiple features are measured for a set of units over time instants. When dealing with such data, flexible statistical … Read more

The seminar series for the Hilary term 2022 commenced with a lightning round session and two presentations from new members of our group, Reme, a post-doctoral researcher and Ultán, a PhD candidate. Reme introduced her thesis topic, which bridges the disciplines of Operations Research and Statistics to develop novel computational methods for the extraction of … Read more

Prof. Mimi Zhang and I recently had a paper accepted to the International Conference on Data Mining 2021 (ERA rank A, Qualis Rank A1). Our paper introduces Density-Core Finding (DCF), an efficient and robust density-based clustering method. DCF extends the popular Density Peaks Clustering (DPC) method which detects modes as points with high density and … Read more

On December 12th, Prof. Alessio Benavoli presented new work on learning choice functions using a Bayesian model. He included an experiment in the talk, demonstrating an application to multi-objective preferential Bayesian optimisation. Abstract: In practical decision making, there are usually several preference relations that have to be taken into account.  For instance, when choosing among … Read more

On October 21st, Daniel Dempsey presented a paper by Joesph, Du Berger & Bélise entitled ‘Bayesian and Mixed Bayesian/Likelihood Criteria for Sample Size Determination’ to the reading group. Slides summarising the paper are available below.

On October 5th, the seminar series for the Michaelmas term commenced with a talk from Prof. Emilio Porcu of Khalifa University, Abu Dhabi. Prof. Porcu gave an overview of recent developments in spatial statistics, how climate datasets have affected the field, and how reformulating problems in more abstracts terms can make solutions easier to find. … Read more
