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.

Identity Aware Sensor Networks

Christina Fragouli, Suhas Diggavi, Lorenzo Keller, Mahdi Jafari Siavoshani

In a significant class of sensor-network applications, the identities of the reporting sensors constitute the bulk of the communicated data, whereas the message itself can be as small as a single bit---for instance, in many cases, sensors are used to detec ...

Linear Universal Decoder for Compound Discrete Memoryless Channels

Rethnakaran Pulikkoonattu

Shannon in his seminal work \cite{paper:shannon} formalized the framework on the problem of digital communication of information and storage. He quantified the fundamental limits of compression and transmission rates. The quantity \textit{channel capacity} ...

Consensus and collision detectors in radio networks

Seth Gilbert

We consider the fault-tolerant consensus problem in radio networks with crash-prone nodes. Specifically, we develop lower bounds and matching upper bounds for this problem in single-hop radios networks, where all nodes are located within broadcast range of ...

Academic Licensing: a European Study

Dominique Foray, Patrick Gaulé, Annamaria Conti

This paper is an empirical analysis of the impact that different organisational forms of the Technology Transfer Offices (TTOs) in Europe have on their licensing activity. Given the great diversity of organization forms prevailing across European TTOs, our ...

Unconscious Eventual Consistency with Gossips

Rachid Guerraoui, Ron Levy

This paper combines various self-stabilization techniques within a replication protocol that ensures eventual consistency in large-scale distributed systems subject to network partitions and asynchrony. A simulation study shows that the resulting protocol ...

Human-Brain Interface: Signal Processing and Machine Learning

Touradj Ebrahimi, Ulrich Hoffmann

The Electroencephalogram (EEG) is a recording of the electrical potentials generated by brain activity on the scalp. It has been used for decades as a non-invasive tool both in fundamental brain research and in clinical diagnosis. But it is now widely used ...

On Network Correlated Data Gathering

Martin Vetterli, Razvan Cristescu

We consider the problem of correlated data gathering by a network with a sink node and a tree communication structure, where the goal is to minimize the total transmission cost of transporting the information collected by the nodes, to the sink node. Two c ...

Efficient decentralized communications in sensor networks

Razvan Cristescu

This thesis is concerned with problems in decentralized communication in large networks. Namely, we address the problems of joint rate allocation and transmission of data sources measured at nodes, and of controlling the multiple access of sources to a sha ...

PILOT: ProbabilistIc Lightweight grOup communication sysTem for Mobile Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Providing reliable group communication is an ever recurring issue in distributed settings. In mobile ad hoc networks, this issue becomes more significant since all nodes act as peers, while the issue gets even more challenging due to highly dynamic and unp ...

Robots as Assistive Technology - Does Appearance Matter?

This paper studies the effect of a robot’s design (appearance) in facilitating and encouraging interaction of children with autism with a small humanoid robot. The paper compares the children’s level of interaction with and response to the robot in two dif ...
