Performance Analysis of Deep Learning Models for Detection of Autism Spectrum Disorder from EEG Signals

Abstract

Autism Spectrum Disorder (ASD) starts showing symptoms in the early formative years of an individual, affecting brain development and negatively impacting social and communication skills.Subjective diagnostic methods for ASD detection require lengthy questionnaires, trained medical personnel, and occupational therapists, and are subject to observer variability.Recent years have seen a rise in the usage of machine learning techniques for detecting ASD, which stems from a requirement for objective and accurate detection methods.This research analyzes the performance of various deep convolutional architectures for the detection of ASD.The primary objective of this work is to select a method capable of performing automatic feature extraction and classification with a relatively high degree of accuracy.Several experiments were conducted with different stateof-the-art deep architectures, out of which the ResNet50 performed the best, with an average accuracy of 81%.The performances of these architectures were analyzed in terms of precision, recall, and accuracy.
