Autism spectrum disorder (ASD) is an intricate neuropsychiatric brain characterized by social deficits and repetitive behaviors. Deep learning approaches have been applied in clinical or behavioral identification of ASD; most erstwhile models are inadequate their capacity to exploit the data richness. On other hand, classification techniques often solely rely on region-based summary and/or functional connectivity analysis magnetic resonance imaging (fMRI). Besides, biomedical modeling...
