A Novel Method of Marginalisation using Low Discrepancy Sequences for Integrated Nested Laplace Approximations
Paul T. Brown, Chaitanya Joshi, Stephen Joe +1
Recently, it has been shown that approximations to marginal posterior distributions obtained using a low discrepancy sequence (LDS) can outperform standard grid-based methods with…
Insider threat modeling: An adversarial risk analysis approach
Chaitanya Joshi, David Rios Insua, Jesus Rios
Insider threats entail major security issues in geopolitics, cyber risk management and business organization. The game theoretic models proposed so far do not take into account som…
On approximating the shape of one dimensional functions
Chaitanya Joshi, Paul T. Brown, Stephen Joe
Consider an -dimensional function being evaluated at points of a low discrepancy sequence (LDS), where the objective is to approximate the one-dimensional functions that res…
