我是scrakit-learn的新手,目前正在学习NaïveBayes(Multinomial).现在,我正在研究sklearn.feature_extraction.text中的文本向量化,出于某种原因,当我向某些文本进行矢量化时,单词"I"不会出现在输出的数组中.
码:
x_train = ['I am a Nigerian hacker', 'I like puppies']
# convert x_train to vectorized text
vectorizer_train = CountVectorizer(min_df=0)
vectorizer_train.fit(x_train)
x_train_array = vectorizer_train.transform(x_train).toarray()
# print vectorized text, feature names
print x_train_array
print vectorizer_train.get_feature_names()
输出:
1 1 0 1 0
0 0 1 0 1
[u'am', u'hacker', u'like', u'nigerian', u'puppies']
为什么"我"似乎没有出现在功能名称中？当我将其更改为"Ia"或类似的其他内容时,它确实会显示出来.
