Online input design for discrimination of linear models using concave minimization

1 code implementation11 Jan 2024 Jacques Noom, Oleg Soloviev, Carlas Smith, Michel Verhaegen

Stochastic Closed-Loop Active Fault Diagnosis (CLAFD) aims to select the input sequentially in order to improve the discrimination of different models by minimizing the predicted error probability.

In-sector Compressive Beam Alignment for MmWave and THz Radios

no code implementations25 Aug 2023 Hamed Masoumi, Michel Verhaegen, Nitin Jonathan Myers

The essence of our framework lies in the construction of a low-resolution beam codebook to identify the best sector and in the design of the CS matrix for in-sector channel estimation.

Analysis of Orthogonal Matching Pursuit for Compressed Sensing in Practical Settings

no code implementations8 Feb 2023 Hamed Masoumi, Michel Verhaegen, Nitin Jonathan Myers

Orthogonal matching pursuit (OMP) is a widely used greedy algorithm for sparse signal recovery in compressed sensing (CS).

Data-enabled predictive control with instrumental variables: the direct equivalence with subspace predictive control

no code implementations12 Sep 2022 Jan-Willem van Wingerden, Sebastiaan Mulders, Rogier Dinkla, Tom Oomen, Michel Verhaegen

Direct data-driven control has attracted substantial interest since it enables optimization-based control without the need for a parametric model.

Structured Sensing Matrix Design for In-sector Compressed mmWave Channel Estimation

no code implementations23 May 2022 Hamed Masoumi, Nitin Jonathan Myers, Geert Leus, Sander Wahls, Michel Verhaegen

Fast millimeter wave (mmWave) channel estimation techniques based on compressed sensing (CS) suffer from low signal-to-noise ratio (SNR) in the channel measurements, due to the use of wide beams.

Nonuniform Defocus Removal for Image Classification

no code implementations3 Jun 2021 Nguyen Hieu Thao, Oleg Soloviev, Jacques Noom, Michel Verhaegen

We propose and study the single-frame anisoplanatic deconvolution problem associated with image classification using machine learning algorithms, named the nonuniform defocus removal (NDR) problem.
