In recent years, there has been a growing prevalence of deep learning in various domains, owing to advancements in information technology and computing power. Graph neural network methods within deep learning have shown remarkable capabilities in processing graph-structured data, such as social networks and traffic networks. As a result, they have garnered significant attention from researchers.However, real-world data often face challenges like data sparsity and missing labels, which can hinder the performance and generalization ability of graph convolutional neural networks. To overcome these challenges, our research aims to effectively extract the hidden features and topological information of graph convolutional neural networks. We propose an innovative model called Adaptive Feature and Topology Graph Convolutional Neural Network (AAGCN). By incorporating an adaptive layer, our model preprocesses the data and integrates the hidden features and topological information with the original data's features and structure. These fused features are then utilized in the convolutional layer for training, significantly enhancing the expressive power of graph convolutional neural networks.To evaluate the effectiveness of the adaptive layer in the AAGCN model, we conducted node classification experiments on real datasets. The results validate its ability to address data sparsity and improve the classification performance of graph convolutional neural networks.In conclusion, our research primarily focuses on addressing data sparsity and missing labels in graph convolutional neural networks. The proposed AAGCN model, which incorporates an adaptive layer, effectively extracts hidden features and topological information, thereby enhancing the expressive power and classification performance of these networks.
近年来,由于信息技术和计算能力的进步,深度学习在各个领域的应用越来越广泛。深度学习中的图神经网络方法在处理图结构数据(如社交网络和交通网络)方面表现出了卓越的能力。因此,它们受到了研究人员的广泛关注。然而,现实世界的数据常常面临数据稀疏和标签缺失等挑战,这可能会阻碍图卷积神经网络的性能和泛化能力。为了克服这些挑战,我们的研究旨在有效地提取图卷积神经网络的隐藏特征和拓扑信息。我们提出了一种创新模型,称为自适应特征和拓扑图卷积神经网络(AAGCN)。通过引入一个自适应层,我们的模型对数据进行预处理,并将隐藏特征和拓扑信息与原始数据的特征和结构进行整合。然后,这些融合后的特征被用于卷积层进行训练,显著增强了图卷积神经网络的表达能力。为了评估AAGCN模型中自适应层的有效性,我们在真实数据集上进行了节点分类实验。结果验证了其解决数据稀疏问题和提高图卷积神经网络分类性能的能力。总之,我们的研究主要集中在解决图卷积神经网络中的数据稀疏和标签缺失问题。所提出的AAGCN模型通过引入自适应层,有效地提取了隐藏特征和拓扑信息,从而增强了这些网络的表达能力和分类性能。
