Talk:Nearest neighbor search

From Wikipedia, the free encyclopedia

I think so ... Issue is this. How can there reduce a candidate and used to kind of distance method? So and how can there apply to it in Ubiquitous envirnment(LBS)?

I apply for k-NN on multiple location based sevice. I make it Hk-NN(Hybrid k-nearest neighbor). That is a mixed method which is a range search and nearest neighbor. Therefore queries processing time was reduced.

I need to hear your opinions for k-NN query method.
