Background:

Resting-state functional MRI (rs-fMRI) is a key tool for autism spectrum disorder (ASD) diagnosis.
Current methods often rely on handcrafted features and single-scale brain network analysis, limiting diagnostic potential.

Purpose of the Study:

To develop a novel multi-scale graph representation learning (MGRL) framework for improved ASD diagnosis from rs-fMRI data.
To overcome limitations of single-scale analysis by integrating information from multiple brain atlases.

Main Methods:

Constructed multi-scale functional connectivity networks (FCNs) using diverse brain atlases.
Employed multi-scale graph convolutional networks (GCNs) for representation learning.
Integrated multi-scale features for ASD classification.

Main Results:

The MGRL framework demonstrated superior performance in feature extraction and ASD identification.
Evaluated on 184 subjects from the Autism Brain Imaging Data Exchange (ABIDE) database.
Outperformed several existing state-of-the-art methods in diagnostic accuracy.

Conclusions:

The proposed MGRL framework effectively leverages multi-scale topological information in FCNs for enhanced ASD diagnosis.
This data-driven approach offers a promising advancement over traditional methods requiring expert knowledge.
