When the skipped word starts from a new line, the pattern is not correctly formed:
Eg. appendiceal\s+orifice\s+were\s{0,1}(\S+\s+){0,1}visualized
The correct pattern should have been:
appendiceal\s+…

I recently posted a paper to arXiv showing that word2vec's Skip Gram with Negative Sampling (SGNS) algorithm is a weighted logistic PCA. With that framework, …

非常感谢您分享的代码。
在skip-gram,我有些问题请教下您,
I_z = {center: 1}这个地方是不是应该是计算context的节点吧,
V = np.array(node_list[contexts]['embedding_vectors']) 应该是计算center的节点embedding吧,
最终更新的是
for z in context_u:
tmp_…

Node2vec and DeepWalk original proposals are built upon the skip-gram model. By default, nodevectors does not set the parameter ```w2vparams["sg"]``` to 1, therefore the underlying Word2Vec model uses…

这种根据中心词来预测中心词的上下文,有什么比较直观的解释吗?像CBOW那种,上下文预测中心词,脑海里想起来比较直观,好理解一些,但是skip-gram模型脑海里却想不到直观的解释,有什么想法或者参考资料吗?
