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.

Dense Depth Estimation from Omnidirectional Images

Pascal Frossard, Zafer Arican

This paper addresses the problem of dense disparity estimation in networks of omnidirectional cameras. We propose to map omnidirectional images on the 2-sphere, and we perform disparity estimation directly on the sphere in order to preserve the geometry of ...

Scientific Computing For Aluminum Production

Jacques Rappaz, Marco Picasso, Gilles Steiner, Thomas Hofer

Numerical simulation in aluminum production envolves many different topics, this paper is dedicated to some aspects of two of them. In the first part, a numerical approach for the computation of the motion of the fluids in an electrolitic cell is presented ...

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 ...

Dynamic urban origin-destination matrix estimation methodology

Emmanuel Bert

The aim of this thesis is to develop a new methodology to determine dynamic Origin-Destination (OD) matrices for urban networks characterized by a high number of traffic hubs, complex route choice possibilities and a high level of traffic controls. By revi ...

What Decision Neuroscience Teaches Us About Financial Decision Making

Financial decision making is the outcome of complex neurophysiological processes involving, among others, constant re-evaluation of the statistics of the problem at hand, balancing of the various emotional aspects, and computation of the very value signals ...

M-DPOP: Faithful distributed implementation of efficient social choice problems

Boi Faltings, Adrian Petcu, David C. Parkes

In the efficient social choice problem, the goal is to assign values, subject to side constraints, to a set of variables to maximize the total utility across a population of agents, where each agent has private information about its utility function. In th ...

Comparison of Methods for Increasing the Performance of a DUA Computation

Computing realistic routes for a given road network and a known demand of vehicles is one of the most important steps when preparing a road traffic simulation. The approach developed by Christian Gawron in 1998 which we use for this purpose computes a dyna ...

On Achieving Periodic Joint-Motion for Redundant Robots

Denis Gillet, Philippe Müllhaupt, Yvan Michellod

The consequence of the loss of involutivity of a specific set of vector fields on the periodicity of the joint motion is examined for redundant robots. An output task, defined as a one dimensional periodic closed curve embedded in a two dimensional working ...

Comparing performance and quality of traffic assignment techniques for microscopic road traffic simulations

Focusing on the tradeoff between accuracy of the assignment and computation time this paper proposes different traffic assignment methods targeting at microscopic traffic simulation. The corresponding network-wide performance indices, the generated route s ...

Computational models in the debate over language learnability

Frédéric Kaplan

Computational models have played a central role in the debate over language learnability. This article discusses how they have been used in different stances, from generative views to more recently introduced explanatory frameworks based on embodiment, cog ...
