Abstract

Recently, numerous estimation issues have been solved due to the developments in data-driven artificial neural networks (ANN) and graph neural networks (GNN). The primary limitation of previous methodologies has been the dependence on data that can be structured in a grid format. However, physiological recordings often exhibit irregular and unordered patterns, posing a significant challenge in conceptualising them as matrices. As a result, GNNs which comprise interactive nodes connected by edges whose weights are defined by anatomical junctions or temporal relationships have received a lot of consideration by leveraging implicit data that exists in a biological system. Additionally, our study incorporates a structural GNN to effectively differentiate between different degrees of infection in both the left and right hemispheres of the brain. Subsequently, demographic data are included, and a multi-task learning architecture is devised, integrating classification and regression tasks. The trials used an authentic dataset, including 800 brain x-ray pictures, consisting of 560 instances classified as moderate cases and 240 instances classified as severe cases. Based on empirical evidence, our methodology demonstrates superior performance in classification, surpassing other comparison methods with a notable achievement of 92.27% in terms of area under the curve as well as a correlation coefficient of 0.62.

基于图神经网络的医学图像智能诊断模型
近年来,由于数据驱动的人工神经网络(ANN)和图神经网络(GNN)的发展,许多估计问题得到了解决。以前的方法的主要限制是依赖于可以以网格格式结构化的数据。然而,生理记录经常表现出不规则和无序的模式,这对将它们概念化为矩阵提出了重大挑战。因此,gnn包含由边连接的交互节点,其权重由解剖连接或时间关系定义,通过利用生物系统中存在的隐式数据得到了很多考虑。此外,我们的研究纳入了结构性GNN,以有效区分大脑左右半球不同程度的感染。在此基础上,结合人口统计数据,设计了一种集分类和回归任务于一体的多任务学习架构。试验使用了一个真实的数据集,包括800张脑x线照片,其中560例被分类为中度病例,240例被分类为重度病例。基于经验证据,我们的方法在分类方面表现出优越的性能,优于其他比较方法,在曲线下面积方面取得了92.27%的显著成绩,相关系数为0.62。
