Bayesian networks and information theory for audio-visual perception modeling

Jonas Richiardi, Patricia Besson

Thanks to their different senses, human observers acquire multiple information coming from their environment. Complex cross-modal interactions occur during this perceptual process. This article proposes a framework to analyze and model these interactions t ...

Anthropic Correction of Information Estimates

Michael Christoph Gastpar

A novel estimator for mutual information is proposed. The estimator is useful for the (asymmetric) scenario where only a few samples for one random variable are available, but for each sample, the conditional distribution of the other random variable can b ...

In this paper we find properties that are shared between two seemingly unrelated lossy source coding setups with side information. The first setup is when the source and side information are jointly Gaussian and the distortion measure is quadratic. The sec ...

Side-Information Scalable Source Coding

Suhas Diggavi

We consider the problem of side-information scalable (SI-scalable) source coding, where the encoder constructs a two-layer description, such that the receiver with high quality side information will be able to use only the first layer to reconstruct the so ...

This paper studies the price of an asset depending on both a fundamental and possible interventions of an authority. Using the martingale approach in continuous time, we provide closed-form solutions to switching problems involving irreversible, state depe ...

On the Heegard-Berger/Kaspi problem with decoder cooperation

Dinkar Vasudevan

We consider decoder cooperation in the Heegard-Berger/Kaspi problem. The encoder sends a common description of a source to two decoders, one of which has side information. Cooperation between the two decoders is of the form of a limited capacity link from ...

D-475 days, on the way towards the Library of the Rolex Learning Center of the Ecole Polytechnique Fédérale de Lausanne, Switzerland

David Aymonin

EPFL is bulduing its Rolex Learning Center, which will be inaugurated in 2010. Point of entry to EPFL, the Learning Center will be a place where to learn, to obtain information, and to live. It will become a place where virtual and physical components comb ...

Simple technique to achieve fast light in gain regime using Brillouin scattering

Luc Thévenaz, Sang Hoon Chin

We describe a novel technique based on stimulated Brillouin scattering for propagating fast light (signal advancement) with low distortion in optical fibers. The essence of the technique relies on the presence of two separate gain resonances in the Brillou ...
