Special Session on
“Recent Trends on Hypercomplex-valued Neural Networks”

Aim and Scope

Hypercomplex-valued neural networks (HvNNs) constitute a growing area of research that has attracted continued interest over the past decades. Unlike traditional real-valued networks, HvNNs treat multidimensional data as a single entity. There are several new research directions on HvNNs: from the formal generalization of commonly used real-valued models to their mathematically richer hypercomplex-valued counterparts to the use of appropriate activation functions that can significantly increase neuron and network functionalities. There are also many exciting applications of HvNNs in pattern recognition and classification, non-linear filtering, intelligent image processing, natural language processing, brain-computer interfaces, time series prediction, bioinformatics, robotics, etc.

The broad class of HvNNs includes complex-valued neural networks (CvNNs) and quaternion-valued neural networks (QvNNs) as examples. Essential characteristics of CvNNs are the proper treatment of the phase and the information contained in the phase and an excellent capability to cope with wave-related phenomena such as electromagnetism, light waves, quantum waves, and oscillatory phenomena. QvNNs, which have potential applications in three-dimensional and four-dimensional data modeling, have been effectively used for multivariate image processing and analysis, such as color and polarimetric SAR images; generation of synthetic data, such as text, video, image, or sound; and for natural language processing, with an emphasis on automatic speech recognition and opinion mining.

We hope this special session will inaugurate a fertile locus at the ICETCI to share recent research results and future works on HvNNs. We also hope this session will inspire and generate benefits for the community of researchers in Computational Intelligence.

This special session welcomes theoretical and applied contributions to hypercomplex-valued neural networks and related fields, including but not limited to the following topics:

  • Dynamics of hypercomplex-valued Hopfield neural networks;
  • Image processing and analysis using HvNNs;
  • Natural language processing and analysis using HvNNs;
  • Approximation properties and efficient learning rules for HvNNs;
  • Deep hypercomplex-valued networks and their applications;
  • Applications of HvNNs for healthcare and medical diagnosis;
  • Applications of HvNNs for Industry 4.0 and cybersecurity;
  • Applications of HvNNs for remote sensing.
