TF-IDF Vectorizer NLP Part I | Understanding NLP with TF-IDF Vectorizer |TF-IDF Vectorizer
TF-IDF (Term Frequency-Inverse Document Frequency) vectorization is a technique used in natural language processing (NLP) to convert a collection of text documents into numerical vectors. This process is crucial for machine learning algorithms to work with text data.
Here's a breakdown of TF-IDF vectorization:
Term Frequency (TF):
Term Frequency measures how often a term occurs in a document.
It is calculated as the ratio of the number of times a word appears in a document to the total number of words in that document.

Number of times term t appears in document d
Inverse Document Frequency (IDF):
IDF measures the importance of a term in the entire document collection.
Terms that appear frequently across all documents are penalized, while terms that are rare or unique are given higher weights.
