Graph Chatbot

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.

Secure Positioning in Sensor Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in sensor and ad hoc networks has been studied in a non-adversarial setting. We show that most of the proposed positioning algorithms are highly vulnerable to attacks from compromised network nodes and malicious (outside) ...

From Set Membership to Group Membership: A Separation of Concerns

André Schiper

We revisit the well-known group membership problem, and show how it can be considered a special case of a simpler problem, the set membership problem. In the set membership problem, processes maintain a set whose elements are drawn from an arbitrary univer ...

Cluster synchronization in three-dimensional lattices of diffusively coupled oscillators

Martin Hasler, Igor Belykh

Cluster synchronization modes of continuous time oscillators that are diffusively coupled in a three-dimensional (3-D) lattice are studied in the paper via the corresponding linear invariant manifolds. Depending in an essential way on the number of oscilla ...

Modeling Human Interaction in Meetings

Hervé Bourlard, Daniel Gatica-Perez, Samy Bengio, Guillaume Lathoud, Darren Moore, Florent Monay Michaud

This paper investigates the recognition of group actions in meetings by modeling the joint behaviour of participants. Many meeting actions, such as presentations, discussions and consensus, are characterised by similar or complementary behaviour across par ...

Dielectric constants of Zr silicates: A first-principles study

Alfredo Pasquarello, Angelo Bongiorno

Using density-functional theory, we compute the optical and static dielectric constants for a set of Zr silicates modeled by various SiO2 crystals, with Zr atoms substitutional to Si, and by an amorphous structure. We then derive a microscopic scheme that ...

DNA binding specificity of different STAT proteins. Comparison of in vitro specificity with natural target sites

Philipp Bucher

STAT transcription factors are expressed in many cell types and bind to similar sequences. However, different STAT gene knock-outs show very distinct phenotypes. To determine whether differences between the binding specificities of STAT proteins account fo ...

Calibration of Spectral Reaction Data

Dominique Bonvin, Michael Amrhein

Calibration is the first step in the prediction of concentrations from spectral measurements of chemical reaction systems. It is a well-known fact that the species in the calibration set must include those in the new set. Typically, the calibration set is ...

Combinatorial Approach for Data Binarization

This paper addresses the problem of transforming arbitrary data into binary data. This is intended as preprocessing for a supervised classification task. As a binary mapping compresses the total information of the dataset, the goal here is to design such a ...
