Sparse Coding with Earth Mover's Distance for Multi-Instance Histogram Representation

no code implementations9 Feb 2015 Mohua Zhang, Jianhua Peng, Xuejie Liu, Jim Jing-Yan Wang

It attempts to represent the feature vector of a data sample by reconstructing it as the sparse linear combination of some basic elements, and a $L_2$ norm distance function is usually used as the loss function for the reconstruction error.
