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.

Consistent Cooperative Localization

Alexander Bahr

In cooperative navigation, teams of mobile robots obtain range and/or angle measurements to each other and dead-reckoning information to help each other navigate more accurately. One typical approach is moving baseline navigation, in which multiple Autonom ...

Graph-Based Distributed Control for Non-holonomic Vehicles Engaged in a Reconfiguration Task using Local Positioning Information

Alcherio Martinoli, Sven Adrian Gowal, Riccardo Falconi

Formation building and keeping among vehicles has been studied for many years, since 1987 with Reynold's rules. This paper presents a control algorithm, based on recent work in graph theory, able to reconfigure static formations of non-holonomic vehicles e ...

Sampling Urban Mobility through On-line Repositories of GPS Tracks

We analyze urban mobility by relying on the short-term mobility traces gathered from a publicly available web-based repository of GPS tracks - the Nokia Sports Tracker service. All mobility traces are obtained from a set of kml files. We show how the data ...

Learning and Predicting Multimodal Daily Life Patterns from Cell Phones

Daniel Gatica-Perez, Katayoun Farrahi

In this paper, we investigate the multimodal nature of cell phone data in terms of discovering recurrent and rich patterns in people's lives. We present a method that can discover routines from multiple modalities (location and proximity) jointly modeled, ...

A Distortion-based Metric for Location Privacy

Jean-Pierre Hubaux, Murtuza Jadliwala, Julien Freudiger, Reza Shokri

We propose a novel framework for measuring and evaluating location privacy preserving mechanisms in mobile wireless networks. Within this framework, we first present a formal model of the system, which provides an efficient representation of the network us ...

Modeling Route Choice Behavior From Smart-phone GPS data

Michel Bierlaire, Jingmin Chen, Jeffrey Newman

Abstract GPS capable smart phones are emerging survey tools in transportation research field, especially in modeling individuals' mobility patterns. In route choice modeling, path observations need to be generated explicitly for the estimation. It is a cha ...

On the Optimal Placement of Mix Zones

Jean-Pierre Hubaux, Julien Freudiger, Reza Shokri

In mobile wireless networks, third parties can track the location of mobile nodes by monitoring the pseudonyms used for identification. A frequently proposed solution to protect the location privacy of mobile nodes suggests to change pseudonyms in regions ...

Physical-virtual linkage with contextual bookmarks

Xavier Righetti

In our everyday life we often see objects or persons and are aware that there are related digital services such as an online ticket service when seeing a poster advertising a concert. Currently it is a rather time consuming activity to find the related inf ...
