Signal Recovery by Stochastic Optimization [PDF]

open access: yesAutomation and Remote Control, 2019
We discuss an approach to signal recovery in Generalized Linear Models (GLM) in which the signal estimation problem is reduced to the problem of solving a stochastic monotone variational inequality (VI). The solution to the stochastic VI can be found in a computationally efficient way, and in the case when the VI is strongly monotone we derive finite ...

Demosaicing using optimal recovery [PDF]

open access: yesIEEE Transactions on Image Processing, 2005
Color images in single-chip digital cameras are obtained by interpolating mosaiced color samples. These samples are encoded in a single-chip charge-coupled device by sampling the light after it passes through a color filter array (CFA) that contains different color filters (i.e., red, green, and blue) placed in some pattern.

On the Optimal Recovery of Graph Signals

open access: yes2023 International Conference on Sampling Theory and Applications (SampTA), 2023
Learning a smooth graph signal from partially observed data is a well-studied task in graph-based machine learning. We consider this task from the perspective of optimal recovery, a mathematical framework for learning a function from observational data that adopts a worst-case perspective tied to model assumptions on the function to be learned.

An Optimal Tree-Structured Repair Scheme of Multiple Failure Nodes for Distributed Storage Systems

open access: yesIEEE Access, 2021
To reduce recovery cost of repairing multiple failed nodes, many repair schemes have been proposed for erasure codes based distributed storage systems. However, most of the existing researches ignore the network topology of storage devices.

The role of multi-fidelity modelling in adaptation and recovery of engineering systems

open access: yesActa Polytechnica CTU Proceedings, 2022
Significant research has been conducted in identifying optimal recovery and adaptation decisions in disruptive scenarios using engineering models. In this context, an aspect that has been target of limited research is that of response times. Modelling is

Optimizing Quantization for Lasso Recovery

open access: yesIEEE Signal Processing Letters, 2018
This letter is focused on quantized Compressed Sensing, assuming that Lasso is used for signal estimation. Leveraging recent work, we provide a framework to optimize the quantization function and show that the recovered signal converges to the actual signal at a quadratic rate as a function of the quantization level.

Design Optimization Methodology for Diversion Structure with Concrete Cofferdam Using Risk-Based Least-Cost Design Method

open access: yesApplied Sciences, 2023
The optimal size of a diversion structure should be carefully studied to ensure economic viability and safety during construction. In practice, to determine the size of a diversion structure, design flood frequency is selected as the suggested return ...
