What is Vectorization ?

We all know that computer understand binary language in the form of 0’s and 1’s. It is impossible to make them understand words naturally. But encoding such words into numeric form can solve our problem.

The process of converting textual information into numbers is called Vectorization. It is also termed as feature extraction.

Different ways to convert text into numbers are: Sparse Vector Representations and Dense Vector Representations

Note: The GitHub codes of this blog are available. To know how to process data before making its representation, go to this blog.

Hello Everyone!

This blog is exclusively for beginners who are willing to start their journey in NLP. I have tried to explain things in an extremely easy manner to give you a smooth start.

After successfully completing the first step, the next step involves extracting features from the text for further analysis. All this will be explained here, so let’s get started!!!

This blog introduces you to…
