This paper presents a median based classifier which predicts the conditional median of the class label given the feature vector. The class label is defined through a hidden variable whose median is further modeled as an additive model of the feature vector. We propose to estimate the conditional median of the hidden variable given the feature vector in the framework of generic functional gradient algorithm  . An equivalent form of the definition of median is introduced, whose smootheddoi:10.5244/c.25.130 dblp:conf/bmvc/Zheng11 fatcat:7qukbgukxjburdbuv2qm3h7l3y
