On decomposability and subdifferential of the tensor nuclear norm

Jiewen Guan, Bo Jiang, Zhening Li

We study the decomposability and the subdifferential of the tensor nuclear norm. Both concepts are well understood and widely applied in matrices but remain unclear for higher-orde…

$ℓ_{p}$ -sphere covering and approximating nuclear $p$ -norm

Jiewen Guan, Simai He, Bo Jiang +1

The spectral $p$ -norm and nuclear $p$ -norm of matrices and tensors appear in various applications albeit both are NP-hard to compute. The former sets a foundation of $ℓ_{p}$ -spher…
