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.

Inferring competitive role patterns in reality TV show through nonverbal analysis

Daniel Gatica-Perez

This paper introduces a new facet of social media, namely that depicting social interaction. More concretely, we address this problem from the perspective of nonverbal behavior-based analysis of competitive meetings. For our study, we made use of “The Appr ...

Voices of Vlogging

Daniel Gatica-Perez, Joan Isaac Biel Tres

Vlogs have rapidly evolved from the ’chat from your bedroom’ format to a highly creative form of expression and communication. However, despite the high popularity of vlogging, automatic analysis of conversational vlogs have not been attempted in the liter ...

Support Vector Machines with a Reject Option

We consider the problem of binary classification where the classfier may abstain instead of classifying each observation. The Bayes decision rule for this setup, known as Chow’s rule, is deﬁned by two thresholds on posterior probabilities. From simple desi ...

New generic approach for the analysis of energy conversion system models

François Maréchal, Helen Carla Becker, Raffaele Bolliger

This paper proposes a new approach in the field of energy conversion systems analysis and synthesis. The method is based on a generic and multi-platform description syntax, that clearly separates the information concerning the physical behavior of the mode ...

Study of Ωc 0 and Ωc * 0 baryons at Belle

Olivier Schneider, Chao Wang, Tagir Aushev, Vladislav Balagura, Xiao Wang

We report results from a study of the charmed double strange baryons Ωc 0 and Ωc * 0 at Belle. The Ωc 0 is reconstructed using the Ωc 0 → Ω- π+ decay mode, and its mass is measured to be (2693.6 ± 0.3-1.5 +1.8) MeV / c2. The Ωc * 0 baryon is reconstructe ...

Feedback loop conception methodology for step-down continuous switching DC/DC converter

Maher Kayal, Stefano Michelis

The stability and the dimensioning of a step-down switching voltage regulator feedback loop remain a complex task. An analytical approach allows dimensioning of all the components, strongly facilitating this task. In this article, a mathematical analysis i ...

Reference-based vs. task-based evaluation of human language technology

Andrei Popescu-Belis

This paper starts from the ISO distinction of three types of evaluation procedures – internal, external and in use – and proposes to match these types to the three types of human language technology (HLT) systems: analysis, generation, and interactive. The ...

Distributed Coverage: From Deterministic to Probabilistic Models

Alcherio Martinoli, Nicolaus Correll

For the multi-robot coverage problem determin- istic deliberative as well as probabilistic approaches have been proposed. Whereas deterministic approaches usually provide provable completeness and promise good performance under perfect conditions, probabil ...
