Object Data Driven Discovery

Prof. Ian Dryden of the University of Nottingham will give the third annual David Finney lecture on June 10th at 6pm in the Bayes Centre. The title of the talk will be Object Data Driven Discovery. 

This annual lecture is in memory of Prof. David Finney, who was the first Professor of Statistics at the University of Edinburgh and who passed away in 2018. The theme of these lectures will be "Statistics and its benefit to society".

The lecture is organised by the Centre of Statistics, which brings together data-driven researchers from across the University of Edinburgh and Associated Institutions, in order to build the capacity needed to address key scientific and societal challenges. The CfS aims to deepen mutual understanding between statisticians working in the mathematical sciences and researchers in other disciplines, leading both to cutting-edge interdisciplinary research that utilises modern statistical tools, and to innovations in statistical research.

Abstract: Object data analysis is an important tool in the many disciplines where the data have much richer structure than the usual numbers or vectors. An initial question to ask is: what are the most basic data units? i.e. what are the atoms of the data? We describe an introduction to this topic, where the statistical analysis of object data has a wide variety of applications. An important aspect of the analysis is to reduce the dimension to a small number key features while respecting the geometry of the manifold in which objects lie. Three case studies are given which exemplify the types of issues that are encountered: i) investigating differences between authors in corpus linguistics, ii) describing changes in variability in damaged DNA, iii) testing for geometrical differences in carotid arteries, where patients are at high or low risk of aneurysm. In all three applications the structure of the data manifolds is important, in particular the manifolds of networks, covariance matrices, and unlabelled size-and-shapes.
