Sparse and Parametric Modeling with Applications to Acoustics and Audio
Recent advances in signal processing, machine learning and deep learning with sparse intrinsic structure of data have paved the path for solving inverse problems in acoustics and audio. The main task of this thesis was to bridge the gap between the powerfu ...
EPFL2020Public Strategies for Artificial Intelligence: Which Value Drivers?
Marie-Valentine Renée Agnès Florin, Gianluigi Viscusi
We question the values that inform the artificial intelligence (AI) strategies developed by governments and institutions at the global level. In particular, we investigate the connection between governments? and institutions? fundamental values, second-ord ...
IEEE COMPUTER SOC2020Graph Signal Processing for Machine Learning: A Review and New Perspectives
Pascal Frossard, Michael Bronstein, Laura Toni, Xiaowen Dong
The effective representation, processing, analysis, and visualization of large-scale structured data, especially those related to complex domains, such as networks and graphs, are one of the key questions in modern machine learning. Graph signal processing ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Timing-Driven Placement for FPGA Architectures with Dedicated Routing Paths
Paolo Ienne, Grace Zgheib, Stefan Nikolic
The idea of introducing dedicated, fast paths between certain FPGA elements in order to reduce delay is neither new nor particularly hard to come up with. What is less obvious, however, is how to put such paths to actual use. In this work, we propose an ef ...
IEEE2020Scalable Convex Optimization Methods for Semidefinite Programming
With the ever-growing data sizes along with the increasing complexity of the modern problem formulations, contemporary applications in science and engineering impose heavy computational and storage burdens on the optimization algorithms. As a result, there ...
EPFL2019Assessing motorcycle taxi activity in Cameroon using GPS devices
Jérôme Chenal, Armel Firmin Kemajou Mbianda, Martí Bosch Padrós, Rémi Jaligot
The emergence of motorcycle taxis as a mode of urban transport in Africa can be seen as a bottom-up response to the larger problem of a demand that is not sufficiently met by public services. Transcending the debates regarding the relevance of this solutio ...
2019Managerial challenges of co-creation and social innovation: the case of Dokk1
Innovation in the public sector is the only possible response to fine-tune welfare services to new and changing demands and overcome policy impasses (Halmos et al., 2019; Misuraca & Colombo, 2016; Misuraca & Viscusi, 2015). According to a growing evidence, ...
2019Semi-Rigidity of Through-Tenon Joints under Tension and Shear Loads and Perpendicular-to-Grain Compression
Yves Weinand, Aryan Rezaei Rad, Anh Chi Nguyen
This report presents the results of experimental tests performed on through-tenon joints used in double-layered and double-curved timber plate shells recently developed. Three tests were carried out to determine the semi-rigidity of these wood-wood connect ...
Laboratory for Timber Constructions IBOIS2019Dynamic Average Diffusion With Randomized Coordinate Updates
Ali H. Sayed, Bicheng Ying, Kun Yuan
This work derives and analyzes an online learning strategy for tracking the average of time-varying distributed signals by relying on randomized coordinate-descent updates. During each iteration, each agent selects or observes a random entry of the observa ...
