Latest version of LMNN (includes non-linear gradient boosted LMNN).
Previous version of LMNN2.4 (outdated)
New and improved version of LMNN. Now runs more stable and has much fewer dependencies. Should be faster on multi-core machines. Now with pre-compiled binaries for Linux, Mac and Windows. (This code was uploaded on 09/18/2012, please let me know if you run into any problems installing or running it. Thanks.)
Code for Large Margin Nearest Neighbors
