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.

Caching (a pair of) Gaussians

Michael Christoph Gastpar, Guillaume Jean Op 't Veld

A source produces i.i.d. vector samples from a Gaussian distribution, but the user is interested in only one component. In the cache phase, not knowing which component the user is interested in, a first compressed description is produced. Upon learning the ...

Function Computation over Networks

Chien-Yi Wang

This thesis looks at efficient information processing for two network applications: content delivery with caching and collecting summary statistics in wireless sensor networks. Both applications are studied under the same paradigm: function computation ove ...

Designing ASCY-compliant Concurrent Search Data Structures

Rachid Guerraoui, Vasileios Trigonakis, Tudor Alexandru David, Tong Che

This report details the design of two new concurrent data structures, a hash table, called CLHT, and a binary search tree (BST), called BST-TK. Both designs are based on asynchronized concurrency (ASCY), a paradigm consisting of four complementary programm ...

Faster Software Cryptography

Dag Arne Osvik

This thesis presents work on the efficiency and security of cryptographic software. First it describes several efforts to construct very efficient implementations of cryptographic primitives. These include the Advanced Encryption Standard (AES) as well as ...

MaSM: Efficient Online Updates in Data Warehouses

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis, Radu Ioan Stoica

Data warehouses (DW) have been traditionally optimized for readonly query performance, allowing only offline updates at night, essentially trading off data freshness for performance. The need for 24x7 operations in global markets and the rise of online and ...

Optimal service pricing for a cloud cache

Anastasia Ailamaki, Grégory François, Debabrata Dash, Sofia Kyriakopoulou

Cloud applications that offer data management services are emerging. Such clouds support caching of data in order to provide quality query services. The users can query the cloud data, paying the price for the infrastructure they use. Cloud management nece ...

Efficient Cache Attacks on AES, and Countermeasures

Dag Arne Osvik

We describe several software side-channel attacks based on inter-process leakage through the state of the CPU's memory cache. This leakage reveals memory access patterns, which can be used for cryptanalysis of cryptographic primitives that employ data-depe ...

Drivolution: Rethinking the Database Driver Lifecycle

George Candea, Emmanuel Cecchet

The current design of database drivers – a necessary evil for interacting with a DBMS – imposes undue burdens on those who install, upgrade, and manage database systems and their applications. In this paper, we introduce Drivolution, a new architecture for ...

Reputation-Based Content Dissemination for User Generated Wireless Podcasting

Jean-Yves Le Boudec

User-generated podcasting service over human-centric opportunistic network can facilitate user-generated content sharing while humans are on the move beyond the coverage of infrastructure networks. We focus on the aspects of designing efficient forwarding ...
