Autism Spectrum Disorder (ASD) requires a precise diagnosis in order to be managed and rehabilitated. Non-invasive neuroimaging methods are disease markers that can used help diagnose ASD. The majority of available techniques the literature use functional magnetic resonance imaging (fMRI) detect ASD with small dataset, resulting high accuracy but low generality. Traditional supervised machine learning classification algorithms such as support vector machines function well unstructured semi structured data text, images, videos, their performance robustness restricted by size accompanying training data. Deep on other hand creates an artificial neural network learn make intelligent judgments its own layering algorithms. It takes plentiful low-cost computing many approaches focused very big datasets concerned creating far larger more sophisticated networks.
