Functional structural equation models with out-of-sample guarantees
Philip Kennerberg, Ernst C. Wit
Statistical learning methods typically assume that the training and test data originate from the same distribution, enabling effective risk minimization. However, real-world applic…
Functional worst risk minimization
Philip Kennerberg, Ernst C. Wit
The aim of this paper is to extend worst risk minimization, also called worst average loss minimization, to the functional realm. This means finding a functional regression represe…
A local barycentric version of the Bak-Sneppen model
Philip Kennerberg, Stanislav Volkov
We study the behaviour of the interacting particle system, arising from the Bak-Sneppen model and Jante's law process. Let vertices be placed on a circle, such that each vertex…
Convergence in the -contest
Philip Kennerberg, Stanislav Volkov
We study asymptotic properties of the following Markov system of points in~. At each time step, the point farthest from the current centre of mass, multiplied by…
