Development of an Efficient and Flexible Pipeline for Lagrangian Coherent Structure Computation
Siavash Ameli, Yogin Desai, Shawn C. Shadden
The computation of Lagrangian coherent structures (LCS) has become a standard tool for the analysis of advective transport in unsteady flow applications. LCS identification is prim…
A Singular Woodbury and Pseudo-Determinant Matrix Identities and Application to Gaussian Process Regression
Siavash Ameli, Shawn C. Shadden
We study a matrix that arises from a singular form of the Woodbury matrix identity. We present generalized inverse and pseudo-determinant identities for this matrix, which have dir…
Noise Estimation in Gaussian Process Regression
Siavash Ameli, Shawn C. Shadden
We develop a computational procedure to estimate the covariance hyperparameters for semiparametric Gaussian process regression models with additive noise. Namely, the presented met…
Learning Whole Heart Mesh Generation From Patient Images For Computational Simulations
Fanwei Kong, Shawn Shadden
Patient-specific cardiac modeling combines geometries of the heart derived from medical images and biophysical simulations to predict various aspects of cardiac function. However,…
