A Three-Stage Expert System Based on Support Vector Machines for Thyroid Disease Diagnosis.

The article presents a three-stage expert system based on a hybrid support vector machines (SVM) technique for the diagnosis of thyroid disease. The system is compared to the SVM based on the grid search technique (Grid-SVM) and the SVM based on Grid search and principle component analysis (PCA-Grid-SVM), and the use of particle swarm optimization (PSO) to optimize the parameters of an optimal predictor model.
