Breaking Blockchain Rationality with Out-of-Band Collusion

Bryan Alexander Ford, Verónica del Carmen Estrada Galiñanes, Louis-Henri Manuel Jakob Merino, Haoqian Zhang

Blockchain systems often rely on rationality assumptions for their security, expecting that nodes are motivated to maximize their profits. These systems thus design their protocols to incentivize nodes to execute the honest protocol but fail to consider ou ...

Scalable Multi-agent Coordination and Resource Sharing

Panayiotis Danassis

A plethora of real world problems consist of a number of agents that interact, learn, cooperate, coordinate, and compete with others in ever more complex environments. Examples include autonomous vehicles, robotic agents, intelligent infrastructure, IoT de ...

Wasserstein Distributionally Robust Learning

Soroosh Shafieezadeh Abadeh

Many decision problems in science, engineering, and economics are affected by uncertainty, which is typically modeled by a random variable governed by an unknown probability distribution. For many practical applications, the probability distribution is onl ...

Moving on: Is Existenzminimum Still Relevant?

Bruno Marchand

In the inter-war period, progressive architects confronted the building of mass housing with an analogy with rational and functional workplaces. At the 2nd CIAM (Congres Internationaux d'Architecture Moderne), held in Frankfurt in 1929, this was tested aga ...

Data-Driven Inverse Optimization with Incomplete Information

Daniel Kuhn, Peyman Mohajerin Esfahani, Soroosh Shafieezadeh Abadeh, Grani Adiwena Hanasusanto

In data-driven inverse optimization an observer aims to learn the preferences of an agent who solves a parametric optimization problem depending on an exogenous signal. Thus, the observer seeks the agent's objective function that best explains a historical ...

Beyond Classical Resonances. Stockholm Mass-Housing Experiments Before the 1930

Chiara Monterumisi

The goal of the 1930 Stockholm exhibition was to illustrate a national project around dwellings and household goods for the Swedish mass. Indeed, in the manifesto acceptera, the organisers masterminded by Gregor Paulsson, investigated the cultural situatio ...

Degradation mode and criticality analysis based on product usage data

Dimitrios Kyritsis, Paul Xirouchakis

Over the last decade, a rapid development of internet, wireless mobile telecommunication, and product identification technologies make whole product life cycle visible and controllable, which can improve several operational issues over the whole product li ...

A Robust Bayesian Truth Serum for Non-binary Signals

Boi Faltings, Goran Radanovic

Several mechanisms have been proposed for incentivizing truthful reports of a private signals owned by rational agents, among them the peer prediction method and the Bayesian truth serum. The robust Bayesian truth serum (RBTS) for small populations and bin ...

Effective Usage of Computational Trust Models in Rational Environments

Karl Aberer

Computational reputation-based trust models using statistical learning have been intensively studied for distributed systems where peers behave maliciously. However practical applications of such models in environments with both malicious and rational beha ...

Analyzing the Emergence of Semantic Agreement among Rational Agents

Karl Aberer, Zoltán Miklós

Todays complex online applications often require the interaction of multiple services that potentially belong to different business entities. Interoperability is a core element of such an environment, yet not a straightforward one. In this paper, we argue ...

Dual Representation Of Monotone Convex Functions On L-0

We study monotone convex functions psi : L-0 (Omega, F, P) -> (-infinity, infinity] and derive a dual representation as well as conditions that ensure the existence of a sigma-additive subgradient. The results are motivated by applications in economic agen ...

Demystifying Rational Financial Decision-Making : Insights from Neurofinance

Anjali Devi Vanapilli Nursimulu

Is the human brain wired for wealth? The setting is the high-velocity financial environment. Undoubtedly, the development of sophisticated derivative instruments has improved the allocation of risk across economies, highlighting the nexus between banking a ...

Collaborative Location Privacy with Rational Users

Jean-Pierre Hubaux, Mathias Jacques Jean-Marc Humbert, Reza Shokri

Recent smartphones incorporate embedded GPS devices that enable users to obtain geographic information about their surroundings by providing a location-based service (LBS) with their current coordinates. However, LBS providers collect a significant amount ...

Elicitation and Modeling of Operational Human Decision Making in a Supply Chain Context : a Study Based on Participatory Simulation

Souleïman Naciri

Supply chains (SC) are complex systems in which human beings play a key role. Whereas human impact is often taken into account in simulation models in terms of physical flows (material handling, fabrication), it is far less the case in terms of information ...

Using identity premium for cooperation enforcement and whitewashing prevention in rational environments

Karl Aberer

One fundamental issue in existing reputation mechanisms, particularly those in open and decentralized multi-agent systems, is whitewashing attacks by rational providers. If identities are cheap, it is beneficial for a provider to simply defect when selling ...

Learning from EEG Error-related Potentials in Noninvasive Brain-Computer Interfaces

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano

We describe error-related potentials generated while a human user monitors the performance of an external agent and discuss their use for a new type of Brain-Computer Interaction. In this approach, single trial detection of error-related EEG potentials is ...

Essays on individual decision making under uncertainty

This research project is an experimental study of decision-making in very difficult contexts resembling those encountered in financial markets. The starting point was the empirical observation that financial assets are objects of a very complex kind. Speci ...

Mechanisms for Making Crowds Truthful

Boi Faltings, Radu Jurca

We consider schemes for obtaining truthful reports on a common but hidden signal from large groups of rational, self-interested agents. One example are online feedback mechanisms, where users provide observations about the quality of a product or service s ...

Configuring and enhancing measurement systems for damage identification

Ian Smith

Engineers often decide to measure structures upon signs of damage to determine its extent and its location. Measurement locations, sensor types and numbers of sensors are selected based on judgment and experience. Rational and systematic methods for evalua ...
