Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Automatic Analysis of Multimodal Group Actions in Meetings

Daniel Gatica-Perez, Samy Bengio, Guillaume Lathoud, Dong Zhang, Mark Barnard

This paper investigates the recognition of group actions in meetings. A statistical framework is proposed in which group actions result from the interactions of the individual participants. The group actions are modelled using different HMM-based approache ...

Generating Synchronization Contracts for Web Services

Alain Wegmann, Otto Preiss

Component composition and Web-service composition have in common that the usage pattern of a certain black-box component or Web-service needs to be described precisely. Because usually many interactions between the client and the service provider are requi ...

Affine Processes and Applications in Finance

Damir Filipovic

We provide the definition and a complete characterization of regular affine processes. This type of process unifies the concepts of continuousstate branching processes with immigration and Ornstein-Uhlenbeck type processes. We show, and provide foundations ...

Computing the performance of unitary space-time group codes from their character table

Mohammad Amin Shokrollahi

Multiple antennas can greatly increase the data rate and reliability of a wireless communication link in a fading environment. Their success, however, depends on the design of cedes that achieve these promises. It is well known that unitary matrices can be ...

Simulation of Peeling using 3D-Surface Cellular Automata

Stéphane Gobron

This paper describes a method for modeling the natural peeling phenomenon over any 3D surface. Using crack input data—precomputed with a semi-physical solution—this method allows simulating peeling on any type of triangulated 3D object. Our model’s main ad ...

Change detection and background extraction by linear algebra

Touradj Ebrahimi, Emrullah Durucan

Change detection plays a very important role in real-time image analysis, e.g., detection of intruders. One key issue is robustness to varying illumination conditions. We propose two techniques for change detection that have been developed to deal with var ...

Continuous bounded cohomology of locally compact groups

Nicolas Monod

The purpose of this monograph is (a) to lay the foundations for a conceptual approach to bounded cohomology; (b) to harvest the resulting applications in rigidity theory. Of central importance is the new interplay between measure theory, amenability, Banac ...

Une extension de l'algèbre du groupe en théorie des représentations modulaires

For a finite group G, certain G-algebras associated to finite G-sets are studied, which generalize both the group algebra and Drinfeld's double. The modular representation theory of these algebras is considered and a striking reciprocity theorem is proved. ...

Linear Estimation

Ali H. Sayed

This textbook is intended for a graduate-level course and assumes familiarity with basic concepts from matrix theory, linear algebra, and linear system theory. Six appendices at the end of the book provide the reader with enough background and review mater ...
