1.CBOW模型 之前已经解释过,无论是CBOW模型还是skip-gram模型,都是以Huffman树作为基础的.值得注意的是,Huffman树中非叶节点存储的中间向量的初始化值是零向量,而叶节点对应的单词的词向量是随机初始化的. 1.1 训练的流程 那么现在假设我们已经有了一个已经构造好的Huffman树,以及初始化完毕的各个向量,可以开始输入...
skip-gram 对低频词效果更好,cbow 对高频词效果更好 skip-gram 比 cbow 训练速度更慢,cbow 比较快 training algorithm: hierarchical softmax 对低频词词效果更好 negative sampling 对高频词效果更好,对低维度向量效果更好 通常来讲,词向量维度越高越好,但不总是这样窗口大小,skip-gram通常在10左右,cbow通常在...

To address this issue, we present an efficient incremental skip-gram algorithm with negative sampling for dynamic network embedding, and provide a set of theoretical analyses to characterize the performance guarantee. Specifically, we first partition a dynamic network into the updated, including addition...
