    Hi David, i've being watching your videos related to Excel and after a time I noticed one thing: This Machine Learning world uses a lot of fancy words and people try to show that what they are doing is really hard. As millions of people uses Excel in their jobs in a daily matter, you are making these "complex" things with fancy names a lot easier for us. thanks!!!!

      Once I saw the math notation of a naive Bayes formula and I got scared! I tried to understand what people were explaining and I had a hard time haha, watching this video made things SO EASY! The recommender system too! Please keep creating content like this, I'm pretty sure that a lot of people have more familiarity with Excel than other tools! I'll try to learn R just because you suggested!

      Duly noted! Have more Excel-based data mining and analytics content planned.

    I loved your video on naive Bayes. I'm wondering if/how the spreadsheet could be made even more automated. For example, is there a way to have Excel do the word counts in each of the text phrases?

      Great question!
      The representation to which you are referring is known as a "document-term matrix." To my knowledge, creating one of these in Excel would require custom coding (e.g., VBA).
      A far easier solution for Excel users would be to learn how to do this in R. Check out this video on my channel on how learning R programming is easy for Excel users: th-cam.com/video/MNpsyjSuR20/w-d-xo.html

    can you make a video about sentiment analysis

    at first how was the data labeled ham or spam and based on what .. was it manual labeling?

    • @DaveOnData

      Check out the following link. To my reading, it looks like they were manually labeled:

    other question, beside the known sentiment analysis methods, can this method used for sentiment analysis

    • @DaveOnData
      @DaveOnData  3 ปีที่แล้ว +1

      The short answer is yes, provided you have a labeled training set.

      @@DaveOnData i hope you make a video about sentiment analysis because i don't understand how words are weighted and based on what

      Unfortunately, as of right now, I am a business of one person and do not have any work opportunities.

    Dave, I have to admit, this did not work well for me. I followed all the formulas. I took one of the priors, a short sentence which is HAM, and used that same sentence, as a test, word for word, and its calculated result is SPAM.
