Special Issue Information

Dear Colleagues,

Nonlinear estimation is broadly applicable to numerous electronic devices that receive signals and output states to enhance dynamical control. Recent advancements are needed to support the future of air and space avionics, autonomous cars, smart cities, and biomedical applications. This Special Issue is devoted to contemporary techniques and applications that resolve challenges in uncertainty quantification, density analysis, and signal filtering. One of the primary techniques in estimation is the Kalman Filter (KF) from which a variety of novel techniques have enhanced the method for ever more refined performance. However, the specific techniques can be domain dependent based on the data, control, and system they are being applied. Coupled with estimation is the understanding of the capability towards metrics, which characterize the performance of estimation techniques resulting from laboratory simulations to real-world applications.

One of the current challenges facing estimation techniques is scaling for performance results. With the advent of big data from multiple devices, current approaches need to perform in a network of distributed, federated, and decentralized applications. From the multidimensional 1D signals, 2D imaging, 3D volumetric, and 4D temporal analysis to higher dimensions, efficient methods for multiresolution analysis are required. Such situations arise in sonar, radar, video, multispectral and other modalities that are used for the surveillance and control of man-made systems. Likewise, for natural systems, there are a variety of phenomena that can leverage estimation techniques for environment (e.g., seismic, acoustic and weather) monitoring. Estimation supports system design of material awareness (e.g., fabrication, inspection, and characterization) and situational awareness (e.g., tracking, monitoring, filtering). Hence, multiresolution scaling methods should complement the model fidelity, data sampling, and information content to better understand the physical systems being assessed.

The aim of this Special Issue is to focus on advances in nonlinear estimation techniques and applications towards multimodal (e.g., multisensor, multiphenomenology, and multiresolution) data-processing in complex scenarios, software methods, and/or hardware devices.

Submissions to this Special Issue on “Nonlinear Estimation Advancements and Results” are solicited to represent a snapshot of the field’s development by covering a range of topics that include, but are not limited to new methods, algorithms, solutions, and applications in the following areas:

  • Federated, decentralized and distributed filtering;
  • Dynamic data, feature, and decision fusion;
  • Navigation, control, and coordination of autonomous systems;
  • Biomedical, multimedia, and statistical signal processing;
  • Communication, networking, and cyber analysis;
  • Multi-dimensional, multimodal, multi-phenomenology characterization;
  • Signals, data, and information understanding;
  • Space, situation, and environment awareness;
  • Shallow, deep, and temporal machine learning;
  • Real-time algorithms for nonlinear estimation;
  • Hardware-specific implementations of nonlinear estimation.

In the paper, a new adaptive model of a neuron based on the Hindmarsh–Rose third-order model of a single neuron is proposed. The learning algorithm for adaptive identification of the neuron parameters is proposed and analyzed both theoretically and by computer simulation. The proposed algorithm is based on the Lyapunov functions approach and reduced adaptive observer. It allows one to estimate parameters of the population of the neurons if they are synchronized. The rigorous stability conditions for synchronization and identification are presented. Full article

Vital for Space Situational Awareness, Initial Orbit Determination (IOD) may be used to initialize object tracking and associate observations with a tracked satellite. Classical IOD algorithms provide only a point solution and are sensitive to noisy measurements and to certain target-observer geometry. This work examines the ability of a Multivariate GPR (MV-GPR) to accurately perform IOD and quantify the associated uncertainty. Given perfect test inputs, MV-GPR performs comparably to a simpler multitask learning GPR algorithm and the classical Gauss–Gibbs IOD in terms of prediction accuracy. It significantly outperforms the multitask learning GPR algorithm in uncertainty quantification due to the direct handling of output dimension correlations. A moment-matching algorithm provides an analytic solution to the input noise problem under certain assumptions. The algorithm is adapted to the MV-GPR formulation and shown to be an effective tool to accurately quantify the added input uncertainty. This work shows that the MV-GPR can provide a viable solution with quantified uncertainty which is robust to observation noise and traditionally challenging orbit-observer geometries. Full article
