Question > knn algorithm doubt (date: 2010-10-06)
By Manuel Alejandro Mijangos Gonzalez
Hi Kardi, greetings from Mexico. I saw your explanation about the knn algorithm and I think it is very good, I visited other explanations about it but they lacked the clarity and easy to follow of your explanation. Thanks for sharing this. I have a doubt about it, what happens if the some of the neighbors have the same distance, for example the first neighbor has the distance of 1, the second also 1, the third also 1, the fourth 3, the fifth 5, the sixth 5. If I choose k=2, then I should take the classification of the 1st to the fourth included for the voting? Thanks in advance for the answer

Your tutorial is great. It presented it in clear understandable format. However there is one question that I want to ask you, how would you rank if square distance between contains duplicate value?

Answer > Determine Optimum k (date: 2012-02-08)
By kardi
Thanks Lindsey for your comment. You can set up some criteria (such as sum square of error or mean absolute deviation) and run the program for various values of k. The k value that bring the minimum criterion would be the best k for your data.
