Background:

Autism Spectrum Disorder (ASD) diagnosis relies on behavioral observation, risking misdiagnosis.
Quantitative biomarkers are needed for more accurate ASD identification.
Current diagnostic methods lack scalability and objectivity.

Purpose of the Study:

To develop and evaluate a machine learning framework, ASD-DiagNet, for classifying ASD using only fMRI data.
To improve the accuracy and efficiency of ASD diagnosis.
To establish a foundation for quantitative biomarkers in mental health disorders.

Main Methods:

ASD-DiagNet utilizes a joint learning procedure with an autoencoder and single layer perceptron (SLP).
A data augmentation strategy based on linear interpolation was implemented for synthetic dataset generation.
The framework was evaluated on a large, multi-center dataset from the Autism Brain Imaging Data Exchange (ABIDE).

Main Results:

ASD-DiagNet achieved a maximum classification accuracy of 82%, outperforming state-of-the-art methods by up to 28%.
The model demonstrated significant improvements in execution time, completing in 40 minutes compared to 7 hours for other methods.
The approach yielded improved feature quality and optimized model parameters.

Conclusions:

ASD-DiagNet offers a highly accurate and efficient fMRI-based approach for ASD classification.
The framework advances quantitative diagnostic methods for heterogeneous mental disorders.
The developed code is publicly available, promoting further research and development.
