Entropy production and Kullback-Leibler divergence between stationary trajectories of discrete systems

, 2012
The irreversibility of a stationary time series can be quantified using the Kullback-Leibler divergence (KLD) between the probability to observe the series and the probability to observe the time-reversed series.

The numerical study of the solution of the $\Phi_0^4$ model

, 2002
We present a numerical study of the nonlinear system of $\Phi^4_0 $ equations of motion. The solution is obtained iteratively, starting from a precise point-sequence of the appropriate Banach space, for small values of the coupling constant.

Parameter estimation in pair hidden Markov models

, 2005
This paper deals with parameter estimation in pair hidden Markov models (pair-HMMs). We first provide a rigorous formalism for these models and discuss possible definitions of likelihoods.

Analysis of Langevin Monte Carlo via convex optimization

, 2018
In this paper, we provide new insights on the Unadjusted Langevin Algorithm. We show that this method can be formulated as a first order optimization algorithm of an objective functional defined on the Wasserstein space of order $2$.
