Multidimensional Particle Swarm Optimization for Machine Learning and Pattern Recognition (Adaptation, Learning, and Optimization)
Format: PDF / Kindle (mobi) / ePub
For many engineering problems we require optimization processes with dynamic adaptation as we aim to establish the dimension of the search space where the optimum solution resides and develop robust techniques to avoid the local optima usually associated with multimodal problems. This book explores multidimensional particle swarm optimization, a technique developed by the authors that addresses these requirements in a well-defined algorithmic approach.
After an introduction to the key optimization techniques, the authors introduce their unified framework and demonstrate its advantages in challenging application domains, focusing on the state of the art of multidimensional extensions such as global convergence in particle swarm optimization, dynamic data clustering, evolutionary neural networks, biomedical applications and personalized ECG classification, content-based image classification and retrieval, and evolutionary feature synthesis. The content is characterized by strong practical considerations, and the book is supported with fully documented source code for all applications presented, as well as many sample datasets.
The book will be of benefit to researchers and practitioners working in the areas of machine intelligence, signal processing, pattern recognition, and data mining, or using principles from these areas in their application domains. It may also be used as a reference text for graduate courses on swarm optimization, data clustering and classification, content-based multimedia search, and biomedical signal processing applications.

In mathematical terms, let f : S ! R be the objective function from a set S to the real numbers. An optimization technique searches for the extremum point x0 in S such that.

Extension, MD PSO (to be discussed in Chap. 4). Finally, PSO_MDmain.cpp is the main console application, which offers three different entry point functions, main(), two of which are enabled with a compiler flag: BATCH_RUN or MOVING_PEAKS_BENCHMARK. The latter enables a special MD PSO application over a benchmark dynamic environment, which will be presented as the application for Sect. 5.2 in Chap. 5. The compiler flag BATCH_RUN can be enabled so as to test both PSO and/or MD PSO over all the.

MD PSO with FGBF. Over-clustered samples are indicated with * (over-clustering). This is due to the use of a simple but quite impure validity index in (6.1) as the fitness function and for some complex clustering schemes it may, therefore, yield its minimum score at a slightly higher number of clusters. A sample clustering operation validating this fact is shown in Fig. 6.3. Note that the true number of clusters is 10, which is eventually reached at the beginning of the operation, yet the.
