- Abstract:
-
In the modeling of computer-aided diagnosis for autism spectrum disorder (ASD) across multiple centers with domain adaptation methods, unlabeled samples from multiple imaging centers are blended together in the target domain. Traditional domain adaptation methods lack the capability to address the clinical scenario of identifying ASD in blended-target domains. To this end, we propose a knowledge distillation blended-target domain adaptation model. Specifically, the graph convolutional network (GCN) is used as the teacher model and the multilayer perceptron (MLP) is used as the student model. To address distribution differences between source and target domains, a novel adversarial knowledge distillation mechanism is proposed to reduce the distribution difference by adversarially training feature extractors and domain discriminators. At the same time, knowledge distillation is used to enable the teacher model to transfer knowledge to the student model while achieving domain adaptation. The ABIDE dataset is employed to validate the effectiveness of the model. Our method not only reduces the complexity of the network but also achieves a classification accuracy of 69.17% in the blended target domains, surpassing other domain adaptation methods.
