# Robust low-rank tensor regression via truncation and adaptive Huber loss

This paper investigates robust low-rank tensor regression with only finite (1+ϵ)-th moment noise based on the generalized tensor estimation framework proposed by Han et al. (2022). The theoretical result shows that when ϵ≥ 1, the robust estimator possesses the minimax optimal rate. While 1> ϵ>0, the rate is slower than the deviation bound of sub-Gaussian tails.
