摘要:
网络嵌入,或者称为网络表示学习,旨在将网络中的节点映射到表示空间中,生成低维稠密的向量,从而在保留网络结构信息的前提下对网络中的节点进行表示,而后通过已有的机器学习方法解决诸如链接预测、节点分类、社团发现和网络可视化等下游任务.随机游走算法可以很好地探索网络中节点的局部结构,然而之前的基于随机游走的表示学习算法只能为节点产生一种角色嵌入,没有考虑到和不同邻居进行交互时节点扮演的不同角色嵌入.因此,提出一种基于路径相互关注的网络嵌入算法,使用节点随机游走产生的上下文信息,通过注意力机制为每个节点生成上下文相互关注的节点嵌入.在真实数据集上的实验结果表明,与三个经典的网络嵌入算法相比,该算法具有更好的表现.
