#Boosted Sparse Nonlinear Distance Metric Learning

This repository contains R codes for implementing the sDist algorithm in our paper Boosted Nonlinear Nonlinear Metric Learning. See the original paper here.

• The main sDist algorithm is in ./lib/sDist_algorithm.R
• All auxillary functions are saved in ./lib
• An example of using sDist algorithm on the Madelon data is given in main.R
• The Madelon data is stored in ./data
