这两个矩阵都含有V个词向量,也就是说同一个词有两个词向量,哪个作为最终的、提供给其他应用使用的embeddings呢?有两种策略,要么加起来,要么拼接起来。在CS224n的编程练习中,采取的是拼接起来的策略: # concatenate the input and output word vectorswordVectors=np.concatenate((wordVectors[:nWords,:],wordVec...

首先,word2vec可以在百万数量级的词典和上亿的数据集上进行高效地训练;其次,该工具得到的训练结果——词向量(word embedding),可以很好地度量词与词之间的相似性。随着深度学习(Deep Learning)在自然语言处理中应用的普及,很多人误以为word2vec是一种深度学习算法。其实word2vec算法的背后是一个浅层神经网络。另外...
