Optimal scaling for the transient phase of the random walk Metropolis algorithm: The mean-field limit

, 2015
We consider the random walk Metropolis algorithm on $\mathbb{R}^n$ with Gaussian proposals, and when the target probability measure is the $n$-fold product of a one-dimensional law. In the limit $n\to\infty$, it is well known (see [Ann. Appl. Probab.

Unifying and Strengthening Hardness for Dynamic Problems via the Online Matrix-Vector Multiplication Conjecture [PDF]

Symposium on the Theory of Computing, 2015
Consider the following Online Boolean Matrix-Vector Multiplication problem: We are given an n x n matrix M and will receive n column-vectors of size n, denoted by v1, ..., vn, one by one.

On stability conditions of vector \(l_\infty\)-extreme combinatorial problem with Pareto principle of optimality

Journal of Numerical Analysis and Approximation Theory, 2003
We consider the multicriteria problem of combinatorial optimization with partial criteria of the kind MINMAX MODUL. The parameters of criteria are subject to "small" independent perturbations.

On the spectral analysis of second-order Markov chains [PDF]

, 2012
36 pagesInternational audienceSecond order Markov chains which are trajectorially reversible are considered. Contrary to the reversibility notion for usual Markov chains, no symmetry property can be deduced for the corresponding transition operators ...

Public-key cryptosystems from the worst-case shortest vector problem: extended abstract

Symposium on the Theory of Computing, 2009
We construct public-key cryptosystems that are secure assuming theworst-case hardness of approximating the minimum distance on n-dimensional lattices to within small Poly(n) factors.

Martingale Inequalities and Deterministic Counterparts [PDF]

, 2014
We study martingale inequalities from an analytic point of view and show that a general martingale inequality can be reduced to a pair of deterministic inequalities in a small number of variables.

On the long time behavior of stochastic vortices systems [PDF]

, 2013
In this paper, we are interested in the long-time behaviour of stochastic systems of n interacting vortices: the position in R2 of each vortex evolves according to a Brownian motion and a drift summing the influences of the other vortices computed ...
