Explained how to Calculate Term Frequency–Inverse Document Frequency (TF-IDF) with vey simple example. TF-IDF is a statistical measure that evaluates how relevant a word is to a document in a collection of documents.
Explained how to Calculate Term Frequency–Inverse Document Frequency (TF-IDF) with vey simple example. TF-IDF is a statistical measure that evaluates how relevant a word is to a document in a collection of documents. This is done by multiplying two metrics: how many times a word appears in a document, and the inverse document frequency of the word across a set of documents.
It has many uses, most importantly in automated text analysis, and is very useful for scoring words in machine learning and data science algorithms for Natural Language Processing (NLP).
TF-IDF was invented for document search and information retrieval. This method can be uses for text clustering, text classification, and text information retrieval in real life projects and data science tasks.
This video introduces a calculation example of how to get TF-IDF for a corpus consist just of two sentences for a given term. On the top of this video, you should be little familiar with BOW (Bag of Words), Stemming, Stop Words meaning, Semantic Segmentation and related NLP/NLU (Natural Language Understanding techniques).
With this video I did not dive into real Python programming. If you feel that you need such tutorial, let me know in comments.

We gonna use Python OS remove( ) method to remove the duplicates on our drive. Well, that's simple you just call remove ( ) with a parameter of the name of the file you wanna remove done.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
