一个简单而有效的框架- GRAPH RANDOM NEURAL NETWORKS ( GRAND )来解决这些问题。 在GRAND中, 我们首先设计了一种随机传播策略来进行图数据增强。 然后,我们利用一致性正则化来优化不同数据增强中无标签节点的预测一致性。在图基准数据集上的大量实验表明,GRAND在半监督节点分类上显著优于当前最先进的GNN基线。 最后...
graph特征:对于已生成的node feature,使用READOUT聚合生成graph特征;其中READOUT函数可以是简单的平均,或者也可以采用一些更复杂的图池化函数。 2.1.2 模型训练 模型额外增加了一个discriminator模块,判断patch representation和graph representation是否来自于同一张图。 损失函数—最大化MI的目标,Jensen-Shannon MI estimato...
GKD: Semi-supervised Graph Knowledge Distillation for Graph-Independent InferenceThe increased amount of multi-modal medical data has opened the opportunities to simultaneously process various modalities such as imaging and non-imaging data to gain a comprehensive insight into the disease prediction domain...

This paper presents a semi-supervised graph-based method for the classification of hyperspectral images. The method is designed to handle the special characteristics of hyperspectral images, namely, high-input dimension of pixels, low number of labeled samples, and spatial variability of the sp...

You can use a semi-supervised graph-based method to label unlabeled data by using the fitsemigraph function. The resulting SemiSupervisedGraphModel object contains the fitted labels for the unlabeled observations (FittedLabels) and their scores (LabelScores). You can also use the SemiSupervisedGraph...
