Hi All, I'm trying to run KNN on set of standardized inputs and identify 20 neighbors using Euclidean distance or other similar distance. I would like to get top N neighbor, distance between the neighbors and my item as output. I don't have a target variable in my dataset, so I need this procedure to identify my neighbors based only on input space. I have 21K items and 145 variables in my dataset, so I'm also looking for efficiency of the procedure. I tried MBR node in Enterprise miner and PROC DISCRIM in base SAS, but both requires target variable. Can anyone kindly point me to the right procedure that would be helpful to implement my problem. Let me know if any other details are needed. Thanks in advance Regards, Shan
