On the (In)security of Peer-to-Peer Decentralized Machine Learning

Carmela González Troncoso, Mathilde Aliénor Raynal, Dario Pasquini

In this work, we carry out the first, in-depth, privacy analysis of Decentralized Learning-a collaborative machine learning framework aimed at addressing the main limitations of federated learning. We introduce a suite of novel attacks for both passive and ...

Policy-based Exploration of Equilibrium Representations (PEER): A topology grammar for generative conceptual structural design

Ioannis Mirtsopoulos

Design exploration is a creative process that consists of the incremental generation of design candidates. Supported by digital means or not, the process handles the ill-structured nature of design and allows creativity to flourish through diversity of des ...

Microfluidics and cell-free synthetic biology in the development of new diagnostic and therapeutic platforms

Grégoire Michielin

In phenylketonuria, absence or malfunction of the phenylalanine hydroxylase enzyme results in toxic accumulation of phenylalanine in the body. An injectable recombinant enzyme therapy was recently approved and has the potential to improve the quality of li ...

War of Words II: Enriched Models of Law-Making Processes

Patrick Thiran, Matthias Grossglauser, Victor Kristof, Aswin Suresh

The European Union law-making process is an instance of a peer- production system. We mine a rich dataset of law edits and intro- duce models predicting their adoption by parliamentary committees. Edits are proposed by parliamentarians, and they can be in ...

Discrete-Choice Mining of Social Processes

Victor Kristof

Poor decisions and selfish behaviors give rise to seemingly intractable global problems, such as the lack of transparency in democratic processes, the spread of conspiracy theories, and the rise in greenhouse gas emissions. However, people are more predict ...

Can Who-Edits-What Predict Edit Survival?

Matthias Grossglauser, Victor Kristof, Lucas Maystre

As the number of contributors to online peer-production systems grows, it becomes increasingly important to predict whether the edits that users make will eventually be beneficial to the project. Existing solutions either rely on a user reputation system o ...

The Economics of Sharing Markets

Maryam Razeghian Jahromi

Sharing and redistributing assets between individuals has become a noticeable part of the economy. Ownership is no longer the sole mode of consumption and consumers have the option of choosing between ownership and access-based consumption. This change in ...

Controlling and Pricing Shareability

Thomas Alois Weber

In the presence of a peer-to-peer economy, the option of sharing an item is valuable for consumers. By retaining control over the shareability of its products a monopolist can set a sharing tariff in conjunction with the purchase price of the product, in o ...

High-Throughput Step Emulsification for the Production of Functional Materials Using a Glass Microfluidic Device

Esther Amstad

High-volume production of monodisperse droplets is of importance for industrial applications due to increased emulsion stability, precise control over droplet volumes, and the formation of periodic arranged structures. So far, parallelized microfluidic dev ...

Product Pricing in a Peer-to-Peer Economy

Thomas Alois Weber

The emergence of a collaborative economy has been driven by advances in information technology that allow consumers to borrow and rent goods among peers on a secondary sharing market. In a dynamic setting, consumers make intertemporal decisions about purch ...

OpenBuildNet Framework for Distributed Co-Simulation of Smart Energy Systems

Colin Neil Jones, Tomasz Tadeusz Gorecki, Faran Ahmed Qureshi, Altug Bitlislioglu, Xuan Truong Nghiem

The complexity and diversity of future energy systems will require co-simulation solutions that enable the integration of tools from multiple domains for research and development. We introduce an open-source framework, OpenBuildNet, for distributed co-simu ...

SOCIAL MOVEMENTS AND THE EVOLUTION OF THE CITY: THE PRACTICE OF SOCIAL INNOVATION AS EMOTIONAL COGNITION OF URBAN SPACE

Darío Negueruela Del Castillo

The ubiquitous upsurge of urban protests around the world In the last years seems to contradict the equally growing production of literature that deals with the city as a scene of conflict and a device for the production of segregation, reminding us of the ...

Decentralized Planning of Energy Demand for the Management of Robustness and Discomfort

Karl Aberer, Matteo Vasirani

The robustness of smart grids is challenged by unpredictable power peaks or temporal demand oscillations that can cause blackouts and increase supply costs. Planning of demand can mitigate these effects and increase robustness. However, the impact on consu ...

A Self-organized Mechanism of Resource Allocation in P2P Systems

Since the performance of a system of interacting peers depends strongly on their individual contributions, the ratio between their provided and consumed resources should be set in line with the social welfare improvement, without relying on a central coord ...

Using Social Media for Collaborative Learning in Higher Education: A Case Study

Denis Gillet, Na Li

This paper investigates the acceptability of using social media for collaborative learning in the context of higher education. A social media platform, Graasp, is used to support students’ learning activities in a project-based course. An evaluation of Gra ...

Designing peer-to-peer overlays : a small-world perspective

Sarunas Girdzijauskas

The Small-World phenomenon, well known under the phrase "six degrees of separation", has been for a long time under the spotlight of investigation. The fact that our social network is closely-knitted and that any two people are linked by a short chain of a ...

Using Three States for Binary Consensus on Complete Graphs

Etienne Perron, Dinkar Vasudevan, Milan Vojnovic

We consider the binary consensus problem where each node in the network initially observes one of two states and the goal for each node is to eventually decide which one of the two states was initially held by the majority of the nodes. Each node contacts ...

PicShark: Mitigating Metadata Scarcity Through Large-Scale P2P Collaboration

Karl Aberer, Manfred Hauswirth, Philippe Cudré-Mauroux, Adriana Budura

With the commoditization of digital devices, personal information and media sharing is becoming a key application on the pervasive Web. In such a context, data annotation rather than data production is the main bottleneck. Metadata scarcity represents a ma ...

Reputation Systems for Self-Organized Networks

Jean-Yves Le Boudec, Jochen Mundinger, Sonja Buchegger

Self-organized networks such as mobile ad-hoc, Internet-based peer-to-peer, wireless mesh and Fourth Generation (4G) Wireless networks depend on cooperation of nodes. Reputation systems help nodes decide with whom to cooperate and which nodes to avoid. The ...

Towards Fair Event Dissemination

Rachid Guerraoui, Maxime Monod

Event dissemination in large scale dynamic systems is typically claimed to be best achieved using decentralized peer-to-peer architectures. The rationale is to have every participant in the system act both as a client (information consumer) and as a server ...
