A tutorial on Bayesian model averaging for exponential random graph models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...

Geodesics as limits of geodesics on PL-surfaces

, 2007
In this paper, we study the problem of convergence of geodesics on PL-surfaces and in particular on subdivision surfaces. More precisely, if a sequence (T_n) of PL-surfaces converges in distance and in normals to a smooth surface S and if C_n is a ...

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances

Computer Graphics Forum, EarlyView.
We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Periodic geodesics on Riemannian manifolds

, 2021
I will discuss the known results of (1) existence of periodic geodesics on Riemannian manifolds; (2) volume and diameter upper bounds for the length of the shortest periodic geodesics.

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations

Computer Graphics Forum, EarlyView.
Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.

Geodesics in metrical connections

, 1971
To each connection on a Riemannian manifold we define a tensor called the Q-tensor. We prove that two metrical connections have the same geodesics if and only if their Q-tensors are equal.
