Discrete choice modeling in the era of big data
The technological advancements of the past decades have allowed transforming an increasing part of our daily actions and decisions into storable data, leading to a radical change in the scale and scope of available data in relation to virtually any object ...
EPFL2024Ghost imaging using two SPAD array detectors: a parameter study towards the realization of a 3D quantum microscope
Edoardo Charbon, Claudio Bruschini, Paul Mos, Yang Lin
Quantum ghost imaging can be an important tool in making optical measurements. One of the most useful aspects of ghost imaging is the unique ability to correlate two sets of independently collected information. We aim to use the principles of ghost imaging ...
Spie-Int Soc Optical Engineering2024The Sparsity of Cycle Spinning for Wavelet-Based Solutions of Linear Inverse Problems
The usual explanation of the efficacy of wavelet-based methods hinges on the sparsity of many real-world objects in the wavelet domain. Yet, standard wavelet-shrinkage techniques for sparse reconstruction are not competitive in practice, one reason being t ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023SELF-SUPERVISED ISOTROPIC SUPERRESOLUTION FETAL BRAIN MRI
Michaël Unser, Meritxell Bach Cuadra
Superresolution T2-weighted fetal-brain magnetic-resonance imaging (FBMRI) traditionally relies on the availability of several orthogonal low-resolution series of 2-dimensional thick slices (volumes). In practice, only a few low-resolution volumes are acqu ...
New York2023Performance of the MALTA telescope
Edoardo Charbon, Francesco Piro, Abhishek Sharma
MALTA is part of the Depleted Monolithic Active Pixel sensors designed in Tower 180 nm CMOS imaging technology. A custom telescope with six MALTA planes has been developed for test beam campaigns at SPS, CERN, with the ability to host several devices under ...
SPRINGER2023Natural slicks on Lake Geneva: From small-scale effects to large-scale formation and distribution
Low wind speeds (< 4 m/s) are ubiquitous in many water bodies, yet the physical processes occurring at the air-water interface in this range are poorly understood. A notable example is smooth patches on the water surface, known as natural slicks, formed wh ...
EPFL2023Computation of the attenuation function of the lightning return-stroke current from electromagnetic fields measured in a short-duration time-window, Part I: Theoretical investigation
In a recent paper, a procedure to reconstruct the attenuation function of a return-stroke current from the simultaneous measurements of the channel-base current and the radiated electromagnetic fields was presented. One of the assumptions of the whole fram ...
2023Spectral representation of EEG data using learned graphs with application to motor imagery decoding
Dimitri Nestor Alice Van De Ville, Hamid Behjat, Maliheh Miri
Electroencephalography (EEG) data entail a complex spatiotemporal structure that reflects ongoing organi-zation of brain activity. Characterization of the spatial patterns is an indispensable step in numerous EEG processing pipelines. We present a novel me ...
Oxford2023Fault Detection and Diagnosis with Imbalanced and Noisy Data: A Hybrid Framework for Rotating Machinery
Fault diagnosis plays an essential role in reducing the maintenance costs of rotating machinery manufacturing systems. In many real applications of fault detection and diagnosis, data tend to be imbalanced, meaning that the number of samples for some fault ...
MDPI2022Graph Neural Networks With Lifting-Based Adaptive Graph Wavelets
Pascal Frossard, Chenglin Li, Mingxing Xu
Spectral-based graph neural networks (SGNNs) have been attracting increasing attention in graph representation learning. However, existing SGNNs are limited in implementing graph filters with rigid transforms and cannot adapt to signals residing on graphs ...
