(2) LINE, in theory, is a special case of DeepWalk when the size of vertices' context is set to one; (3) As an extension of LINE, PTE can be viewed as the joint factorization of multiple networks' Laplacians; (4) node2vec is factorizing a matrix related to the stationary ...

通俗理解word2vec的训练过程 word2vec是如何得到词向量的? skip-gram中,训练样本的形式是(input word, output word),其中output word是input word的上下文。为了减少模型噪音并加速训练速度,我们在构造batch之前要对样本进行采样,剔除停用词等噪音因素。 神经网络像是一个黑盒子,这其中的概念很难理解,此博主对词...
用gensim doc2vec计算文本相似度 转自: gensim doc2vec + sklearn kmeans 做文本聚类 原文显示太乱 为方便看摘录过来。。 用doc2vec做文本相似度,模型可以找到输入句子最相似的句子,然而分析大量的语料时,不可能一句一句的输入,语料数据大致怎么分类也不能知晓。于是决定做文本聚类。
