Second-Order Converses via Reverse Hypercontractivity
Jingbo Liu, Ramon van Handel, Sergio Verdú
A strong converse shows that no procedure can beat the asymptotic (as blocklength ) fundamental limit of a given information-theoretic problem for any fixed error proba…
Improving constant in end-point Poincaré inequality on Hamming cube
Paata Ivanisvili, Dong Li, Ramon van Handel +1
We improve the constant in -Poincaré inequality on Hamming cube. For Gaussian space the sharp constant in inequality is known, and it is .…
Uniform Time Average Consistency of Monte Carlo Particle Filters
Ramon van Handel
We prove that bootstrap type Monte Carlo particle filters approximate the optimal nonlinear filter in a time average sense uniformly with respect to the time horizon when the signa…
Uniform observability of hidden Markov models and filter stability for unstable signals
Ramon van Handel
A hidden Markov model is called observable if distinct initial laws give rise to distinct laws of the observation process. Observability implies stability of the nonlinear filter w…
Discrete Approximation of Quantum Stochastic Models
Luc Bouten, Ramon van Handel
We develop a general technique for proving convergence of repeated quantum interactions to the solution of a quantum stochastic differential equation. The wide applicability of the…
The stability of conditional Markov processes and Markov chains in random environments
Ramon van Handel
We consider a discrete time hidden Markov model where the signal is a stationary Markov chain. When conditioned on the observations, the signal is a Markov chain in a random enviro…
