Realistic Synthetic Social Networks with Graph Neural Networks

no code implementations15 Dec 2022 Alex Davies, Nirav Ajmeri

Widely applied models are currently rule-based and can struggle to reproduce structural dynamics.

The signature and cusp geometry of hyperbolic knots

no code implementations30 Nov 2021 Alex Davies, András Juhász, Marc Lackenby, Nenad Tomasev

We introduce a new real-valued invariant called the natural slope of a hyperbolic knot in the 3-sphere, which is defined in terms of its cusp geometry.

The Random Forest Kernel and other kernels for big data from random partitions

no code implementations18 Feb 2014 Alex Davies, Zoubin Ghahramani

We present Random Partition Kernels, a new class of kernels derived by demonstrating a natural connection between random partitions of objects and kernels between those objects.
