Short Course on Functional Data Analysis – February 18-19, 2025

Short Course on Functional Data Analysis – February 18-19, 2025
Join us for a two-day short course on Functional Data Analysis, featuring a seminar by Jan Almond Stöcker from EPFL.

Seminar – February 17, 2025

Speaker: Jan Almond Stöcker, EPFL
Title: Functional Additive Models for Forms of Plane Curves and Their Visualization
Time: 14:00 – 16:00

Abstract:
In many imaging data problems, the coordinate system of recorded objects is arbitrary or explicitly not of interest. Statistical shape analysis addresses this by identifying the object of analysis as the “shape” of observation, i.e., its equivalence class modulo translation, rotation, and re-scaling, or as its “form” modulo translation and rotation. This seminar introduces a flexible additive regression framework for modeling the shape or form of planar (potentially irregularly sampled) curves and/or landmark configurations in dependence on scalar covariates. The focus will be on the form of cell outlines generated from a cellular Potts model in relation to different biophysical model parameters and their effects. Additionally, a novel visualization for multidimensional functional regression models will be discussed.
