Asymptotic analysis of rare events in high dimensions

Anya Katsevich, Alexander Katsevich

Understanding rare events is critical across domains ranging from signal processing to reliability and structural safety, extreme-weather forecasting, and insurance. The analysis o…

A unified theory of the high-dimensional Laplace approximation with application to Bayesian inverse problems

Anya Katsevich, Vladimir Spokoiny

The Laplace approximation (LA) to posteriors is a ubiquitous tool to simplify Bayesian computation, particularly in the high-dimensional settings arising in Bayesian inverse proble…

The Laplace asymptotic expansion in high dimensions

Anya Katsevich

We prove that the classical Laplace asymptotic expansion (AE) of , extends to the high-dimensional regime in which may grow large w…

Improved dimension dependence in the Bernstein von Mises Theorem via a new Laplace approximation bound

Anya Katsevich

The Bernstein-von Mises theorem (BvM) gives conditions under which the posterior distribution of a parameter based on independent samples is asympto…

The Laplace approximation accuracy in high dimensions: a refined analysis and new skew adjustment

Anya Katsevich

In Bayesian inference, making deductions about a parameter of interest requires one to sample from or compute an integral against a posterior distribution. A popular method to make…

Tight Bounds on the Laplace Approximation Accuracy in High Dimensions

Anya Katsevich

In Bayesian inference, a widespread technique to compute integrals against a high-dimensional posterior is to use a Gaussian proxy to the posterior known as the Laplace approximati…
