Great explanation. I am an old student of Varun Sir. He taught my batch a subject in Gate Gurus in the year 2016 for GATE. Now I am pursuing Masters in USA and I went on to YouTube to find the best explanation of this topic. After getting bored from other tutorials, I was excited to open this one and to my pleasure, this is the best one, and I listened the whole attentively. Power of social media. Thanks a ton Sir for making this accessible at no cost to a vast audience.

Hello Sir. Thanks for the explanation. Your videos have helped me understand many concepts and clear my exams . I have one question here. In this example Time of movie is having higher weightage then the rating due to difference of scales. Do we need to normalize them to give equal weightage?

It refers to that "DATA TUNING" is done on the basis of "DATA-DENSITY".
