Random tensor isomorphism under orthogonal and unitary actions

Jeremy Chizewer, Samuel Everett, Deven Mithal +1

We study the problem of testing whether two tensors in ${\mathbb{R}}^{\ell }\otimes {\mathbb{R}}^m\otimes {\mathbb{R}}^n$ are isomorphic under the natural action of orthogonal groups $\text…
