Journal Article
Quaternion neural network with geometrical operators
TL;DR: This paper shows by experiments that the quaternion-version of the Back Propagation algorithm achieves correct geometrical transformations in three-dimensional space, as well as in color space for an image compression problem, whereas real-valued BP algorithms fail.
Book ChapterDOI
Quaternion Neural Network and Its Application
TL;DR: This paper shows by experiments that the quaternion-version of the Back Propagation (BP) algorithm achieves correct geometrical transformations in color space for an image compression problem, whereas real-valued BP algorithms fail.
Journal ArticleDOI
Associative memory in quaternionic Hopfield neural network.
TL;DR: Associative memory networks based on quaternionic Hopfield neural network are investigated and it is clarified that there exist at most 16 stable states, called multiplet components, as the degenerated stored patterns, and each of these states has its basin in the quaternion networks.
Journal ArticleDOI
Fault-tolerance in nanocomputers: a cellular array approach
TL;DR: This paper advances asynchronous cellular arrays that are tolerant to transient errors in up to one third of the information stored by its cells, implying less complexity of the cells as compared to a previously proposed (nonfault-tolerant) asynchronous cellular array that employs nine rules.
Book ChapterDOI
Quaternionic Neural Networks: Fundamental Properties and Applications
TL;DR: The application of complex numbers to neural networks has recently attracted attention because they tend to improve the learning ability and conform to the abovementioned applications.
