I. Word meaning Meaning的定义有很多种,其中有: the idea that is represented by a word,phrase,etc. the idea that a person wants to express by using words, signs, etc. 1.Discrete representation 那么在计算机中是如何获取一个word的meaning的呢?常见的解决办法是使用像WordNet之类的数据集,它包含了同义词(synonym…

I. 复习word2vec的核心思路 1. Skip-gram 模型示意图: 2.word vectors的随机梯度 假设语料库中有这样一行句子: I love deep learning and NLP 中心词为deep,那么在计算梯度的时候则可以得到如下的梯度向量. 可以很明显地看到该向量非常稀疏.常见的解决办法有两种:一是使用稀疏矩阵更新运算来更新矩阵\(U,V\)的特定的列向量.二是使用哈希来更新,即key为word string,value是对应的列向量. II. 近似 1. 负采样…

The amazing power of word vectors | the morning paper (acolyer.org) What is a word vector? At one level, it's simply a vector of weights. In a simple 1-of-N (or 'one-hot') encoding every element in the vector is associated with a word in the vocabula…
