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.

Incremental Adaptive Strategies Over Distributed Networks

Ali H. Sayed

An adaptive distributed strategy is developed based on incremental techniques. The proposed scheme addresses the problem of linear estimation in a cooperative fashion, in which nodes equipped with local computing abilities derive local estimates and share ...

Diffusion Least-Mean Squares Over Adaptive Networks

Ali H. Sayed

Distributed adaptive algorithms are proposed to address the problem of estimation in distributed networks. We extend recent work by relying on static and adaptive diffusion strategies. The resulting adaptive networks are robust to node and link failures an ...

A High Throughput Atomic Storage Algorithm

Rachid Guerraoui, Dejan Kostic, Ron Levy

This paper presents an algorithm to ensure the atomicity of a distributed storage that can be read and written by any number of clients. In failure-free and synchronous situations, and even if there is contention, our algorithm has a high write throughput ...

Adaptive processing over distributed networks

Ali H. Sayed

The article describes recent adaptive estimation algorithms over distributed networks. The algorithms rely on local collaborations and exploit the space-time structure of the data. Each node is allowed to communicate with its neighbors in order to exploit ...

A class of algorithms for distributed constraint optimization

Adrian Petcu

Multi Agent Systems (MAS) have recently attracted a lot of interest because of their ability to model many real life scenarios where information and control are distributed among a set of different agents. Practical applications include planning, schedulin ...

Efficient Distributed Subtyping Tests

Rachid Guerraoui, João Barreto, Patrick Eugster

Subtyping tests are essential in typed publish/subscribe infrastructures, especially when the underlying programming language supports subtype conformance, as in Java or C#. These tests are particularly challenging when the publish/subscribe infrastructure ...

Distributed Sender-Driven Video Streaming

Pascal Frossard

A system for sender-driven video streaming from multiple servers to a single receiver is considered in this paper. The receiver monitors incoming packets on each network path and returns, to the senders, estimates of the available bandwidth on all the netw ...

Distributed SVM applied to image classification

Pascal Frossard, Effrosyni Kokiopoulou

This paper proposes an algorithm for distributed classification, based on a SVM scheme. The contribution of each support vector is approximated by low complexity distributed thresholding over sub-dictionaries, whose union forms a redundant dictionary of at ...

Global Sensor Networks

Karl Aberer, Manfred Hauswirth, Ali Salehi

The availability of cheap and smart wireless sensing devices provides unprecedented possibilities to monitor the physical world. On the technical side these devices introduce several original research problems, many of them related to the integration of th ...

A middleware for fast and flexible sensor network deployment

Karl Aberer, Manfred Hauswirth, Ali Salehi

A key problem in current sensor network technology is the heterogeneity of the available software and hardware platforms which makes deployment and application development a tedious and time consuming task. To minimize the unnecessary and repetitive implem ...
