5.4 Term Frequency-Inverse Document Frequency (TF-IDF)

TF-IDF is the multiplication of the TF and IDF which we calculated above

5.5 Feature Extraction

We don’t have to calculate TF and IDF every time beforehand and then multiply it to obtain TF-IDF. so, sklearn has a separate function to directly obtain it use of : from sklearn.feature_extraction.text import TfidfVectorizer (library)
