Learning in High-Dimensional Feature Spaces Using ANOVA-Based Fast Matrix-Vector Multiplication

Theresa Wagner, TU Chemnitz

Kernel matrices are crucial in many learning tasks and typically dense and large-scale. Depending on the dimension of the feature space even the compu- tation of all its entries in reasonable time...

Laplacians on Riemann surfaces and Graphs

Noema Nicolussi (Potsdam)

There are many interesting parallels between analysis on Riemann surfaces and graphs. Both settings admit a Laplace operator and the Poisson equation reflects crucial geometric information.

Motivated...

Percolation of the level set of the Gaussian Free Field on a Galton-Watson tree.

Gioele Gallo (Köln)

The study of Gaussian free field level sets on supercritical Galton-Watson trees has been initiated by Abächerli and Sznitman. We continue this investigation by means of different tools in order to...
