Nonlinear Biomedical Signal Processing: Fuzzy Logic, Neural Networks, and New Algorithms (1) (IEEE Press Series in Biome
For the first time, eleven experts in the fields of signal processing and biomedical engineering have contributed to an edition on the newest theories and applications of fuzzy logic, neural networks, and algorithms in biomedicine. Nonlinear Biomedical Signal Processing, Volume I provides comprehensive coverage of nonlinear signal processing techniques. In the last decade, theoretical developments in the concept of fuzzy logic have led to several new approaches to neural networks. This compilation delivers plenty of real-world examples for a variety of implementations and applications of nonlinear signal processing technologies to biomedical problems. Included here are discussions that combine the various structures of Kohenen, Hopfield, and multiple-layer "designer" networks with other approaches to produce hybrid systems. Comparative analysis is made of methods of genetic, back-propagation, Bayesian, and other learning algorithms.
Topics covered include:
- Uncertainty management
- Analysis of biomedical signals
- A guided tour of neural networks
- Application of algorithms to EEG and heart rate variability signals
- Event detection and sample stratification in genomic sequences
- Applications of multivariate analysis methods to measure glucose concentration
Why Read This Book
You should read this book if you need a focused survey of nonlinear approaches applied to real biomedical signals — it shows how fuzzy logic, neural nets, chaos measures and other nonlinear tools have been used for feature extraction, classification and interpretation. The chapters give practical case studies (ECG, EEG, EMG) and algorithm-level descriptions that help bridge theory to biomedical DSP practice.

How It Compares
Compared with Rangayyan's Biomedical Signal Analysis, which emphasizes classical feature extraction and statistics, Akay's volume focuses more on nonlinear, fuzzy and neural methods and provides an edited collection of application case studies; Sörnmo & Laguna is more practical for ECG processing pipelines, whereas Akay emphasizes alternative nonlinear paradigms.
