    I want to thank you, I've been watching your videos for a few months. I speak Spanish, and my English is not the best, because of your accent at first I thought I would never understand them because I had never heard that accent, but now I end up studying more English to be able to watch your videos faster. Thank you for your dedication and being part of the creators who democratize their knowledge, leaving everything in videos that are free for us.

      See the big words you’re using and you say you’re learning English.
      I don’t believe you!

    Thanks for the NLP series of videos. Please make a video on domain knowledge gaining. Teach us the domain knowledge wrt Datascience Fine with any specific domain. Also make a video explaining what are the data points to look for choosing a machine learning algorithm for example when do we need to go for Random forest for classification and when for SVM etc. I know you have covered couple these concepts in your earlier videos but a playlist with only these details at deeper level would work. Keep the good work going. Thanks a ton. You are a great inspiration.

    Let C = number of times a given word appears in a document;
    TW = total number of words in a document;
    TD = total number of documents in a corpus, and
    DF = total number of documents containing a given word;
    compute TF, IDF and TF*IDF score for each term

    Correct me if I'm wrong.
    Bag Of Words ( count or Binary ) and TF-IDF will only give the values based on the frequency of the occurance and doesn't process based on semantics. To get the output based on semantics we need to use Word2Vec. @Krish Naik

    Something to be aware of is that TF-IDF cannot help carry semantic meaning. It considers the importance of the words due to how it weighs them, but it cannot necessarily derive the contexts of the words and understand importance that way.

    since there is a possibility that some unseen word could come which is not present in our vocabulary because of which denominator of IDF may become zero right?
