Thank you very much for your video.It is very help full to me.But i have a some confusion,that is when k is multiples of classes only the problem is finding the element belonging class.Is that right?
-
So what about when k=1 and we have 2 classes A and B. We want to to identify a new element x in one of this classes and the distances are equal. Then the algorithm in which class puts the element x?
-
can i use k=2?

Really good, Keep Doing....
-
thank you
-
Your videos were clear and understandable by everyone thanks for putting in your efforts on this :)
-
Thank you! Great video
-
Thanks, clear and perfect!.
-
clear and simple explanation Helped me a lot in supervised classification. thank you!
-
very good short explanations for beginners in field of machine learning.........good job
-
Clear and simple, thanks.
-
Thank you very much
-
what do you do if your KNN has K+ points of equal distances?
-
good explanation with short time...😃
-
explained very well
-
Thanks for the video
-
Which Algorithm should we prefer over K-NN ?
-
Great explanation - clear and simple - thanks much!
-
why k is < 6?
-
In your example, when you find out that 'C' element belongs to 'O' class, if you would like to clasify another element 'D' , is 'C' taken in account to predict the label for 'D' or just the original samples are used to clasify it?
Thanks.
