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.
One of the main differences between modern search engines and traditional ones is the adoption of link-based ranking algorithm in ordering Web documents. Google has claimed that it is its link-based ranking algorithm, PageRank that has made the quality of ...
The link structure of the Web graph is used in algorithms such as Kleinberg's HITS and Google's PageRank to assign authoritative weights to Web pages and thus rank them. In HITS, a solid theoretical model is lacking and the algorithm often leads to non-uni ...
Studies of the Web graph at the granularity of documents have revealed many interesting link distributions. Similarly, studies of the Web graph at the granularity of Web sites, the so-called hostgraph, revealed relationships among hosts based on linkage an ...
The limitations of client/server systems become evident in an Internet-scale distributed environment. Peer-topeer (P2P) systems offer an interesting alternative to traditional client/server systems: Every node acts both as a client and a server and “ ...
We find that there lacks a formal algebraic framework in the research area of P2P information retrieval. Such a formal framework is indispensable and pivotal. On the one hand, no solid theoretical foundation can explain why the results of many ad-hoc comme ...
Nonradiative recombination losses originating from crystallographic distortions and issues occurring upon interface formation are detrimental for the photovoltaic performance of perovskite solar cells. Herein, we incorporated a series of carbamide molecule ...
In this work, we focus on managing scientific environmental data, which are measurement readings collected from wireless sensors. In environmental science applications, raw sensor data often need to be validated, interpolated, aligned and aggregated before ...
This is a COSPAR roadmap to advance the frontiers of science through innovation and international collaboration using small satellites. The world of small satellites is evolving quickly and an opportunity exists to leverage these developments to make scien ...
