Artistic Aspects of the Wigner Caustic and the Centre Symmetry Set
Iza Danielewska, Dawid Poławski, Dominika Sterczewska +1
The Wigner caustic and the Centre Symmetry Set of a closed smooth planar curve are known singular sets which generically admit only cusp singularities. Applications of these object…

Graphical Negative Multinomial and Multinomial Models with Dirichlet-type priors
Iza Danielewska, Bartosz Kołodziejek, Jacek Wesołowski +1
Bayesian statistical graphical models are typically classified as either continuous and parametric (Gaussian, parameterized by the graph-dependent precision matrix with Wishart-typ…
