Fast adaptive tubal-rank-revealing algorithm for t-product based tensor approximation

Color images and video sequences can be modeled as 3-way tensors, which admit low tubal-rank approximations via convex surrogate minimization. This optimization problem is efficiently addressed by tensor singular value thresholding (t-SVT). To mitigate the computational burden of tensor singular value decomposition (t-...
