WebDec 30, 2024 · WMD(Word Mover’s Distance) 1 是2015年提出的一种衡量文本相似度的方法。. 它具有以下几个优点:. 效果出色:充分利用了 word2vec 的领域迁移能力. 无监督:不依赖标注数据,没有冷启动问题. 模型简单:仅需要词向量的结果作为输入,没有任何超参数. 可解释性 ... WebThis is an implementation of the Earth Movers Distance, as described in . The EMD computes the distance between two distributions, which are represented by signatures. The signatures are sets of weighted features that capture the distributions. The features can be of any type and in any number of dimensions, and are defined by the user.
EMD(earth mover
Web在计算机学界,Wasserstein distance很多时候都叫Earth Mover's distance(EMD),在最早的EMD论文(2000)里给出的也是类似 Kantorovich-Wasserstein 的数学形式,也就是说这个东西数学上并不是新东西,我私下觉得这样取个新名字是不好的。. 除了常见的Kantorovich-Wasserstein形式 ... WebWord Mover's Distance basics ¶. WMD is a method that allows us to assess the "distance" between two documents in a meaningful way, even when they have no words in common. It uses word2vec [4] vector embeddings of words. It been shown to outperform many of the state-of-the-art methods in k -nearest neighbors classification [3]. smart energy service gmbh
