Supervised Learning with Complex-valued Neural Networks by Suresh Sundaram, Narasimhan Sundararajan, Ramasamy Savitha


Supervised Learning with Complex-valued Neural Networks by Suresh Sundaram, Narasimhan Sundararajan, Ramasamy Savitha

Recent advancements in the field of telecommunications, medical imaging and signal processing deal with signals that are inherently time varying, nonlinear and complex-valued. The time varying, nonlinear characteristics of these signals can be effectively analyzed using artificial neural networks. Furthermore, to efficiently preserve the physical characteristics of these complex-valued signals, it is important to develop complex-valued neural networks and derive their learning algorithms to represent these signals at every step of the learning process. This monograph comprises a collection of new supervised learning algorithms along with novel architectures for complex-valued neural networks. The concepts of meta-cognition equipped with a self-regulated learning have been known to be the best human learning strategy. In this monograph, the principles of meta-cognition have been introduced for complex-valued neural networks in both the batch and sequential learning modes. For applications where the computation time of the training process is critical, a fast learning complex-valued neural network called as a fully complex-valued relaxation network along with its learning algorithm has been presented. The presence of orthogonal decision boundaries helps complex-valued neural networks to outperform real-valued networks in performing classification tasks. This aspect has been highlighted. The performances of various complex-valued neural networks are evaluated on a set of benchmark and real-world function approximation and real-valued classification problems.

I love Lovereading for the wonderful like for like author recommendations and for highlighting new books, it's a great resource for readers!


Thanks to Lovereading I have discovered new writers and read books I would never had looked twice at - and enjoyed them.

Angela Rhodes

Books of the month/debuts of the month, kids/adults, fiction/non-fiction, free prize draws and free extracts, what's not to love?

Emma Smith

Lovereading has all the new books and also suggestions for 'similar' authors whilst waiting for your favourites new books.

Carol Peace

It's information about new books so, for a book lover like me, what's not to like!

Joan Hill

With literary excellence, humour and drama, Lovereading's got value and is a real stress-calmer!

Siobhan McDowell

Insightful reader reviews and unbiased recommendations. I don't know how I chose books before Lovereading! An essential for all book lovers.

Sarah Harper

Lovereading does a stella job in promoting both new and established authors.
