Invariance of Clustering Operations in Causal Effect Identification
Jani Nykänen, Otto Tabell, Santtu Tikka +1
Clustering variables in causal graphs reduces the size of the graph and simplifies causal inference. However, arbitrary clustering can alter crucial causal relations among variable…

Mean field stochastic differential equations with a diffusion coefficient with irregular distributional dependence
Jani Nykänen
We study mean field stochastic differential equations with a diffusion coefficient that depends on the distribution function of the unknown process in a discontinuous manner, which…

Convergence rate for random walk approximations of mean field BSDEs
Boualem Djehiche, Hannah Geiss, Stefan Geiss +2
We study the rate of convergence w.r.t.~a Wasserstein type distance for random walk approximations of mean field BSDEs. Our method does not use the particle method but instead a fr…
