Spectral Estimators for High-Dimensional Matrix Inference
A key challenge across many disciplines is to extract meaningful information from data which is often obscured by noise. These datasets are typically represented as large matrices. Given the current trend of ever-increasing data volumes, with datasets grow ...
EPFL2024Quantization for Decentralized Learning Under Subspace Constraints
Ali H. Sayed, Stefan Vlaski, Roula Nassif, Marco Carpentiero
In this article, we consider decentralized optimization problems where agents have individual cost functions to minimize subject to subspace constraints that require the minimizers across the network to lie in low-dimensional subspaces. This constrained fo ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Investigation of Self-Sensing Techniques for Dielectric Elastomer Actuators
Self-sensing allows to use a Dielectric Elastomer Actuator (DEA) simultaneously as an actuator and sensor, without the need of external sensors. DEAs are composed of a dielectric elastomer that is sandwiched between two electrodes. If a voltage difference ...
2023State-Based Versus Time-Based Estimation of the Gait Phase for Hip Exoskeletons in Steady and Transient Walking
Auke Ijspeert, Mohamed Bouri, Ali Reza Manzoori, Tian Ye
The growing demand for online gait phase (GP) estimation, driven by advancements in exoskeletons and prostheses, has prompted numerous approaches in the literature. Some approaches explicitly use time, while others rely on state variables to estimate the G ...
IEEE 2023Resolution and penetration depth of reflection-mode time-domain near infrared optical tomography using a ToF SPAD camera
Edoardo Charbon, Martin Wolf, Jingjing Jiang
In a turbid medium such as biological tissue, near-infrared optical tomography (NIROT) can image the oxygenation, a highly relevant clinical parameter. To be an efficient diagnostic tool, NIROT has to have high spatial resolution and depth sensitivity, fas ...

Three-dimensional (3D) knee angle measurement is one of the key measures in human gait analysis. Inertial sensor capable of measuring joint motion under unconstrained conditions is a practical tool for clinical evaluation and rehabilitation. An inertial me ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Diffusion LMS With Communication Delays: Stability and Performance Analysis
We study the problem of distributed estimation over adaptive networks where communication delays exist between nodes. In particular, we investigate the diffusion Least-Mean-Square (LMS) strategy where delayed intermediate estimates (due to the communicatio ...

Jamie Paik, Olivier Lambercy, Harshal Arun Sonar
Stochastic stimulation has been shown to improve movement, balance, the sense of touch, and may also improve position sense. This stimulation can be non-invasive and may be a simple technology to enhance proprioception. In this study, we investigated wheth ...
2020Affine Combination of Diffusion Strategies Over Networks
Diffusion adaptation is a powerful strategy for distributed estimation and learning over networks. Motivated by the concept of combining adaptive filters, this work proposes a combination framework that aggregates the operation of multiple diffusion strate ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Spatially Varying Monte Carlo SURE for the Regularization of Biomedical Images
Jean-Philippe Thiran, Marco Pizzolato
Regularization, filtering, and denoising of biomedical images requires the use of appropriate filters and the adoption of efficient regularization criteria. It has been shown that the Stein’s Unbiased Risk Estimate (SURE) can be used as a proxy for the mea ...
