Node2Vec belongs to Graph Embedding. Detailed info about Graph Embedding is at <>.

node2vec: Scalable Feature Learning for Networks - Stanford2016

node2vec is an algorithmic framework for learning continuous feature representations for nodes in networks. In node2vec, we learn a mapping of nodes to a low-dimensional space of features that maximizes the likelihood of preserving network neighborhoods of nodes.

node2vec主要用于处理网络结构中的多分类和链路预测任务,具体来说是对网络中的节点和边的特征向量表示方法。简单点来说就是将原有社交网络中的图结构,表达成特征向量矩阵,每一个node(人、物或内容等)表示成一个特征向量,用向量与向量之间的矩阵运算来得到相互的关系。
