Facets of Urban Co-Creation
Participation in the context of urban planning is growing in the urban and architectural processes of democratic cities. Urban co-creation means working with communities by integrating their needs, giving them the opportunity to collaborate in the transfor ...
Barcelona2023Social Representations of Mexico City Historic Center: Heritage and Controversial Memories
In this paper, we present the results of a research project that deals with the controversial memories of historic urban landscapes that have been designated as World Heritage sites by UNESCO. We observe - through the study of social representations of Mex ...
JOHANNES KEPLER UNIV, INST PAEDAGOGIK & PSYCHOLOGIE2020Fourier could be a data scientist: From graph Fourier transform to signal processing on graphs
Pierre Vandergheynst, Benjamin Ricaud, Nicolas Tremblay
The legacy of Joseph Fourier in science is vast, especially thanks to the essential tool that the Fourier transform is. The flexibility of this analysis, its computational efficiency and the physical interpretation it offers makes it a cornerstone in many ...
ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER2019Medialab stories: how to align actor network theory and digital methods
Dominique Georges Léon Boullier
The history of laboratories may become controversial in social sciences. In this paper, the story of Sciences Po Médialab told by Venturini et al. is discussed and completed by demonstrating the incoherence in the choice of digital methods at the Médialab ...
2018Unified Theory for Recovery of Sparse Signals in a General Transform Domain
Compressed sensing is provided a data-acquisition paradigm for sparse signals. Remarkably, it has been shown that the practical algorithms provide robust recovery from noisy linear measurements acquired at a near optimal sampling rate. In many real-world a ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2018The Sketching Complexity of Graph and Hypergraph Counting
Mikhail Kapralov, John Michael Goddard Kallaugher
Subgraph counting is a fundamental primitive in graph processing, with applications in social network analysis (e.g., estimating the clustering coefficient of a graph), database processing and other areas. The space complexity of subgraph counting has been ...
IEEE COMPUTER SOC2018From recommender systems to spatio-temporal dynamics with network science
Networks are data structures that are fundamental for capturing and analyzing complex interactions between objects. While they have been used for decades to solve problems in virtually all scientific fields, their usage for data analysis in real-world prac ...
EPFL2017Fixed Points of Generalized Approximate Message Passing with Arbitrary Matrices
The estimation of a random vector with independent components passed through a linear transform followed by a componentwise (possibly nonlinear) output map arises in a range of applications. Approximate message passing (AMP) methods, based on Gaussian appr ...
2016Inference for Generalized Linear Models via Alternating Directions and Bethe Free Energy Minimization
Generalized Linear Models (GLMs), where a random vector x is observed through a noisy, possibly nonlinear, function of a linear transform z = A x arise in a range of applications in nonlinear filtering and regression. Approximate Message Passing (AMP) meth ...
IEEE2015A Dual-Tree Rational-Dilation Complex Wavelet Transform
In this correspondence, we introduce a dual-tree rational-dilation complex wavelet transform for oscillatory signal processing. Like the short-time Fourier transform and the dyadic dual-tree complex wavelet transform, the introduced transform employs quadr ...
