Hi Devan and Xiangrui, Can you please explain the cost and optimization function of the KNN alogorithim that is being used? Thank and Regards, Sudipta On Thu, Jan 22, 2015 at 6:59 PM, DEVAN M.S. wrote: > Thanks Xiangrui Meng will try this. > > And, found this https://github.com/kaushikranjan/

Re: KNN for large data set

Thanks Xiangrui Meng will try this. And, found this https://github.com/kaushikranjan/knnJoin also. Will this work with double data ? Can we find out z value of *Vector(10.3,4.5,3,5)* ? On Thu, Jan 22, 2015 at 12:25 AM, Xiangrui Meng wrote: > For large datasets, you need hashing in order to

Re: KNN for large data set

For large datasets, you need hashing in order to compute k-nearest neighbors locally. You can start with LSH + k-nearest in Google scholar: http://scholar.google.com/scholar?q=lsh+k+nearest -Xiangrui On Tue, Jan 20, 2015 at 9:55 PM, DEVAN M.S. wrote: > Hi all, > > Please help me to find out best

KNN for large data set

Hi all, Please help me to find out best way for K-nearest neighbor using spark for large data sets.
