Hi,
How do I interpret the results of the TfidfVectorizer? For example:
from sklearn.feature_extraction.text import TfidfVectorizer
data = ['see spot run', 'run spot run']
vectorizer = TfidfVectorizer()
X = vectorizer.fit_transform(data)
print(X)
produces:
(0, 0)0.501548907094
(0, 2)0.501548907094
(0, 1)0.704909488931
(1, 0)0.894427191
(1, 2)0.4472135955
I understand from the docs that this is a sparse matrix. However, I'm
unsure how to interpret it. For example, if I wanted the tfidf score
of each word in `data`, could I get that from the sparse matrix?
Thanks,
Adam
