In the 10th question, how figure b is also correct? I think we can only optimize one parameter at a time. Please explain
Explain the correct answer
Hey @HemantKumar, extremely sorry for delay at my end. Actually yes we can optimize two parameters also at a time. You can imagine the clustering algorithm on 2D plane only. For centers there are two points namely x coordinate, and y coordinate. After single iteration we update centers, this means we update x as well as y. So you can see here we are optimizing two parameters at a time.
Hope this resolved your doubt. 
Plz mark your doubt as resolved in my doubts section.
