Designing Artificial Neural Networks Using Particle Swarm Optimization Algorithms.

The review approach involves evaluating three distinct swarm-based algorithms for automated model configuration. Researchers systematically test Basic Particle Swarm Optimization, Second Generation of Particle Swarm Optimization, and the NMPSO model. The team defines eight unique fitness functions to assess candidate solutions during the evolutionary process. These functions incorporate mean square error and classification error to guide the search. The design strategy prioritizes the simultaneous refinement of weights, architecture, and transfer functions. Investigators compare their automated results against manual configurations created via Back-Propagation and Levenberg-Marquardt techniques. The study validates these models using various nonlinear pattern classification problems. This comprehensive evaluation ensures that the proposed framework maintains high accuracy across diverse scenarios.

Key findings from the literature indicate that the automated methodology successfully evolves all three principal network components. The swarm-based models demonstrate the ability to identify optimal synaptic weights, connections, and transfer functions concurrently. Researchers report that the eight proposed fitness functions effectively mitigate risks associated with overtraining. The data shows a significant reduction in connection density compared to standard manual design approaches. The proposed NMPSO model exhibits robust performance across various nonlinear pattern classification challenges. Comparisons reveal that these automated designs achieve accuracy levels competitive with traditional Back-Propagation and Levenberg-Marquardt learning algorithms. The results suggest that simultaneous optimization yields more efficient network architectures. These findings highlight the effectiveness of swarm intelligence in streamlining complex computational design tasks.

The authors propose that their automated methodology successfully evolves multiple network components simultaneously.
