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.

Collaborative coverage using a swarm of networked miniature robots

Alcherio Martinoli, Nicolaus Correll, Samuel Rutishauser

We study distributed coverage of environments with unknown extension using a team of networked miniature robots analytically and experimentally. Algorithms are analyzed by incrementally raising the abstraction level starting from physical robots, to realis ...

NEARCTIS - Role of technologies: Positioning and Communication

Pierre-Yves Gilliéron

Positioning, tracking and communication (PTC) systems are the basic components of cooperative systems, and it is their development in recent years that has in turn made possible the idea of cooperative systems. The ongoing developments of GNSS (Global Navi ...

Gaussian Diamond Network with Adversarial Jammer

Suhas Diggavi, Soheil Mohajerzefreh

In this paper we consider communication from a source to a destination over a wireless network with the help of a set of authenticated relays. We focus on a special ``diamond'' network, where there is no direct link between the source and the destination; ...

Learning collaborative manipulation tasks by demonstration using a haptic interface

Aude Billard, Sylvain Calinon, Elena Gribovskaya

This paper presents a method by which a robot can learn through observation to perform a collaborative manipulation task, namely lifting an object. The task is first demonstrated by a user controlling the robot's hand via a haptic interface. Learning extra ...

Innovations Diffusion: A Spatial Sampling Scheme for Distributed Estimation and Detection

Ali H. Sayed

We consider a wireless network with distributed processing capabilities for estimation or detection applications. Due to limited communication resources, the network selects only a subset of sensor measurements for estimation or detection as long as the re ...

Mobility-centric design of collaborative transportation systems

Embedded sensors and actuators are revolutionizing the way we perceive and interact with the physical world. Current research on such Cyber-Physical Systems (CPSs) has focused mostly on distributed sensing and data gathering. The next step is to move from ...

Segregation in swarms of mobile robots based on the Brazil nut effect

Francesco Mondada, Stéphane Magnenat, Roderich Gross

We study a simple algorithm inspired by the Brazil nut effect for achieving segregation in a swarm of mobile robots. The algorithm lets each robot mimic a particle of a certain size and broadcast this information locally. The motion of each particle is con ...

A General Characterization of Indulgence

Rachid Guerraoui

An indulgent algorithm is a distributed algorithm that, besides tolerating process failures, also tolerates unreliable information about the interleaving of the processes. This article presents a general characterization of indulgence in an abstract comput ...

Toward Massive Query Optimization in Large-Scale Distributed Stream Systems

Karl Aberer

Existing distributed stream systems adopt a tightly-coupled communication paradigm and focus on fine-tuning of operator placements to achieve communication efficiency. This kind of approach is hard to scale (both to the nodes in the network and the users). ...

Multisensory integration of dynamic voices and faces in the monkey brain

Henry Markram, Catherine Perrodin

[...] Primates are social animals whose communication is based on their conspecifics' vocalizations and facial expressions. Although a lot of work to date has studied the unimodal representation of vocal or facial information, little is known about the way ...
