论文摘要
数据集是自闭症疾病研究深度学习的关键。但是,由于当前数据集中样品的数量和异质性很少,例如遵守(自闭症脑成像数据交换),因此识别研究不够有效。先前的研究主要集中于优化特征选择方法和数据加强以提高准确性。本文基于后一种技术,该技术通过GraphRNN了解了真实大脑网络的边缘分布,并生成了对判别模型具有激励作用的合成数据。实验结果表明,原始数据和合成数据的组合大大改善了神经网络的歧视。例如,最重要的效果是50层重新系统,最好的生成模型是GraphRNN,与没有生成数据加强的模型参考实验相比,它的精度提高了32.51%。由于生成的数据来自自闭症患者的学习边缘连接分布和典型的控制功能连接性,但其效果比原始数据更好,这对于进一步了解疾病机制和发育具有建设性的意义。
Dataset is the key of deep learning in Autism disease research. However, due to the few quantity and heterogeneity of samples in current dataset, for example ABIDE (Autism Brain Imaging Data Exchange), the recognition research is not effective enough. Previous studies mostly focused on optimizing feature selection methods and data reinforcement to improve accuracy. This paper is based on the latter technique, which learns the edge distribution of real brain network through GraphRNN, and generates the synthetic data which has incentive effect on the discriminant model. The experimental results show that the combination of original and synthetic data greatly improves the discrimination of the neural network. For instance, the most significant effect is the 50-layer ResNet, and the best generation model is GraphRNN, which improves the accuracy by 32.51% compared with the model reference experiment without generation data reinforcement. Because the generated data comes from the learned edge connection distribution of Autism patients and typical controls functional connectivity, but it has better effect than the original data, which has constructive significance for further understanding of disease mechanism and development.
