词典准备好之后,我们就可以对训练集里的每一封邮件提取维度是 3000 的词数向量 word count vector(这个向量就是我们的特征),每一个词数向量都包含之前选定的 3000 个高频词具体的出现频率。当然,你可能猜到了,大部分出现的频率应该会是 0。举个栗子:比如我们字典里有 500 个词,每个词数向量包含了训练集里这 ...
Python stringis a sequence of characters. If within any of your programming applications, you need to go over the characters of a string individually, you can use the for loop here. Here’s how that would work out for you. word="anaconda"forletterinword:print(letter) ...
Let’s use a conditional frequency distribution to examine the differences in word lengths for a selection of languages included in the udhr corpus. The output is shown in Figure 2-2 (run the program yourself to see a color plot). Note that True and False are Python’s built-in Boolean ...
