Hi,
I have a data marix D in size of Nxd where N is the number of samples (lets say 50,000) and d is a sample dimention (lets say 10)
I would like to perfome a KNN search over the sample but with "search window" that means for each sample i want to find its KNN but only among the C closet samples in D.
For example if K=3 and C=20, i would like to find the 3 NN of sample i among sample [i-10,i+10]
does anyone know how can i do it?
Thanks
