Pytorch softmax mlp
Web针对链路预测，R-GCN在关系图中的多个推理过程中采用编码器模型来积累信息，可以显著地优化链路预测模型；对于实体分类任务，R-GCN对每个节点使用一个softmax分类器，通过卷积网络来提取每个节点的表示，用于对节点类别做出预测。 但是随着关系数的增多,模型会引入过多关系矩阵Wr，导致参数爆炸，模型难以训练。 CompGCN是针对多关系图提出的异 … WebFeb 15, 2024 · Implementing an MLP with classic PyTorch involves six steps: Importing all dependencies, meaning os, torch and torchvision.
