Abstract: Sjogren|s syndrome is a chronic inflammatory process that primarily involves the exocrine glands. Clinical manifestations range from autoimmune exocrinopathy to extraglandular involvement affecting the lungs, kidneys, blood vessels and muscles; Sjogren|s syndrome can occur along with, or accompany, other autoimmune diseases. Moreover, diagnosing Sjogren|s syndrome saves lives. The term support vector machine (SVM) refers to an emerging machine learning technique based on statistical learning theory which can solve classification problems using small sampling, non-linearity and high dimensions. However, both dimension reduction and parameter determination greatly influence the performance of the SVM technique. Therefore, this study develops a SVM with an immune algorithm (IA) and kernel principal component analysis (KSVMIA) model to diagnose Sjogren|s syndrome effectively and efficiently. In the proposed KSVMIA model, the kernel-based principal component analysis (KPCA) technique is used to reduce the dimension of Sjogren|s syndrome data; the IA is employed to determine the SVM models. Experimental results reveal that the developed model can classify Sjogren|s syndrome data obtained from ultrasound in terms of efficiency and accuracy, showing that the presented KSVMIA model is a promising alternative for diagnosing Sjogren|s syndrome.
