Tensor Methods for Additive Index Models under Discordance and Heterogeneity
Krishnakumar Balasubramanian, Jianqing Fan, Zhuoran Yang
Motivated by the sampling problems and heterogeneity issues common in high- dimensional big datasets, we consider a class of discordant additive index models. We propose method of…
