Classification of Adult Autistic Spectrum Disorder Using Machine Learning Approach

Nurul Amirah Mashudi, Norulhusna Ahmad, Norliza Mohd Noor


Autism Spectrum Disorder (ASD) is a neurological-related disorder. Patients with ASD have poor social interaction and lack of communication that lead to restricted activities. Thus, early diagnosis with a reliable system is crucial as the symptoms may affect the patient’s entire lifetime. Machine learning approaches are an effective and efficient method for the prediction of ASD disease. The study mainly aims to achieve the accuracy of ASD classification using a variety of machine learning approaches. The dataset comprises 16 selected attributes that are inclusive of 703 patients and non-patients. The experiments are performed within the simulation environment and analyzed using the WEKA platform. Linear SVM, k-Nearest Neighbours (k-NN), J48, Bagging, Stacking, AdaBoost, and Naïve Bayes are the methods used to compute the prediction of ASD status on the subject using 3, 5, and 10-folds cross validation. The analysis is then computed to evaluate the accuracy, sensitivity, and specificity of the proposed methods. The comparative result between the machine learning approaches has shown that Linear SVM, J48, Bagging, Stacking, and Naïve Bayes produce the highest accuracy at 100% with the lowest error rate.
