Selected aspects of complex, hypercomplex and fuzzy neural networks
This short report reviews the current state of the research and methodology
on theoretical and practical aspects of Artificial Neural Networks (ANN). It
was prepared to gather state-of-the-art knowledge needed to construct complex,
hypercomplex and fuzzy neural networks.
The report reflects the individual interests of the authors and, by now
means, cannot be treated as a comprehensive review of the ANN discipline.
Considering the fast development of this field, it is currently impossible to
do a detailed review of a considerable number of pages.
The report is an outcome of the Project 'The Strategic Research Partnership
for the mathematical aspects of complex, hypercomplex and fuzzy neural
networks' meeting at the University of Warmia and Mazury in Olsztyn, Poland,
organized in September 2022.Comment: 46 page

Towards NeuroAI: Introducing Neuronal Diversity into Artificial Neural Networks
Throughout history, the development of artificial intelligence, particularly
artificial neural networks, has been open to and constantly inspired by the
increasingly deepened understanding of the brain, such as the inspiration of
neocognitron, which is the pioneering work of convolutional neural networks.
Per the motives of the emerging field: NeuroAI, a great amount of neuroscience
knowledge can help catalyze the next generation of AI by endowing a network
with more powerful capabilities. As we know, the human brain has numerous
morphologically and functionally different neurons, while artificial neural
networks are almost exclusively built on a single neuron type. In the human
brain, neuronal diversity is an enabling factor for all kinds of biological
intelligent behaviors. Since an artificial network is a miniature of the human
brain, introducing neuronal diversity should be valuable in terms of addressing
those essential problems of artificial networks such as efficiency,
interpretability, and memory. In this Primer, we first discuss the
preliminaries of biological neuronal diversity and the characteristics of
information transmission and processing in a biological neuron. Then, we review
studies of designing new neurons for artificial networks. Next, we discuss what
gains can neuronal diversity bring into artificial networks and exemplary
applications in several important fields. Lastly, we discuss the challenges and
future directions of neuronal diversity to explore the potential of NeuroAI
Nonlinear Systems
Open Mathematics is a challenging notion for theoretical modeling, technical analysis, and numerical simulation in physics and mathematics, as well as in many other fields, as highly correlated nonlinear phenomena, evolving over a large range of time scales and length scales, control the underlying systems and processes in their spatiotemporal evolution. Indeed, available data, be they physical, biological, or financial, and technologically complex systems and stochastic systems, such as mechanical or electronic devices, can be managed from the same conceptual approach, both analytically and through computer simulation, using effective nonlinear dynamics methods. The aim of this Special Issue is to highlight papers that show the dynamics, control, optimization and applications of nonlinear systems. This has recently become an increasingly popular subject, with impressive growth concerning applications in engineering, economics, biology, and medicine, and can be considered a veritable contribution to the literature. Original papers relating to the objective presented above are especially welcome subjects. Potential topics include, but are not limited to: Stability analysis of discrete and continuous dynamical systems; Nonlinear dynamics in biological complex systems; Stability and stabilization of stochastic systems; Mathematical models in statistics and probability; Synchronization of oscillators and chaotic systems; Optimization methods of complex systems; Reliability modeling and system optimization; Computation and control over networked systems

Artificial intelligence models for refrigeration, air conditioning and heat pump systems
Artificial intelligence (AI) models for refrigeration, heat pumps, and air conditioners have emerged in recent decades. The universal approximation accuracy and prediction performances of various AI structures like feedforward neural networks, radial basis function neural networks, adaptive neuro�fuzzy inference and recurrent neural networks are encouraging interest. This review discusses existing
topographies of neural network models for RHVAC system modelling, energy prediction and fault(s), and detection and diagnosis. Studies show that AI structures require standardization and improvement for tuning hyperparameters (like weight, bias, activation functions, number of hidden layers and neurons). The selection of activation functions, validation, and learning algorithms depends on author’s
suitability for a particular application. Backpropagation, error trial selection of the number of hidden layer, and hidden layers’ neurons, and Levenberg–Marquardt learning algorithms, remain prevalent
methodologies for developing AI structures. The major limitations to the application of AI models in
RHVAC systems include exploding or/and vanishing gradients, interpretability, and accuracy trade off,
and training saturation and limited sensitivity. This review aims to give up-to-date applications of
different AI architectures in RHVAC systems and to identify the associated limitations and prospect

Advanced Mathematics and Computational Applications in Control Systems Engineering
Control system engineering is a multidisciplinary discipline that applies automatic control theory to design systems with desired behaviors in control environments. Automatic control theory has played a vital role in the advancement of engineering and science. It has become an essential and integral part of modern industrial and manufacturing processes. Today, the requirements for control precision have increased, and real systems have become more complex. In control engineering and all other engineering disciplines, the impact of advanced mathematical and computational methods is rapidly increasing. Advanced mathematical methods are needed because real-world control systems need to comply with several conditions related to product quality and safety constraints that have to be taken into account in the problem formulation. Conversely, the increment in mathematical complexity has an impact on the computational aspects related to numerical simulation and practical implementation of the algorithms, where a balance must also be maintained between implementation costs and the performance of the control system. This book is a comprehensive set of articles reflecting recent advances in developing and applying advanced mathematics and computational applications in control system engineering
