Representation Based Regression for Object Distance Estimation

2 code implementations27 Jun 2021 Mete Ahishali, Mehmet Yamac, Serkan Kiranyaz, Moncef Gabbouj

To the best of our knowledge, this is the first representation-based method proposed for performing a regression task by utilizing the modified CSENs; and hence, we name this novel approach as Representation-based Regression (RbR).
