稀疏向量(SparseVector):可以略去向量中多余的0元素。此时,向量中的每一个元素是一个(key, value)的元组 模型(Model):是一个抽象的术语。定义了两个向量空间的变换(即从文本的一种向量表达变换为另一种向量表达)。 安装:pip install gensim 官网:https://radimrehurek.com/gensim/ ...
Themax()function has akeyparameter that can determine the criteria for the comparison on selecting the maximum element. Themax()function will directly return the index of the maximum element with theitemgetter()function as the value for this parameter. ...
