Query: Identifying Autism Spectrum Disorder Based on Individual-Aware
  Down-Sampling and Multi-Modal Learning   Autism Spectrum Disorder(ASD) is a set of neurodevelopmental conditions that
affect patients' social abilities. In recent years, many studies have employed
deep learning to diagnose this brain dysfunction through functional MRI (fMRI).
However, existing approaches solely focused on the abnormal brain functional
connections but ignored the impact of regional activities. Due to this biased
prior knowledge, previous diagnosis models suffered from inter-site measurement
heterogeneity and inter-individual phenotypic differences. To address this
issue, we propose a novel feature extraction method for fMRI that can learn a
personalized lower-resolution representation of the entire brain networking
regarding both the functional connections and regional activities.
Specifically, we abstract the brain imaging as a graph structure and
straightforwardly downsample it to substructures by hierarchical graph pooling.
To further recalibrate the distribution of the extracted features under
phenotypic information, we subsequently embed the sparse feature vectors into a
population graph, where the hidden inter-subject heterogeneity and homogeneity
are explicitly expressed as inter- and intra-community connectivity
differences, and utilize Graph Convolutional Networks to learn the node
embeddings. By these means, our framework can extract features directly and
efficiently from the entire fMRI and be aware of implicit inter-individual
variance. We have evaluated our framework on the ABIDE-I dataset with 10-fold
cross-validation. The present model has achieved a mean classification accuracy
of 87.62\% and a mean AUC of 0.92, better than the state-of-the-art methods.
