L1 … WebThis outlier sensitivity of Tucker is often attributed to its L2/Frobenius norm based formulation. Contributions: In this line of research, we set theoretical foundations and develop algorithms for reliable L1-norm based tensor analysis. Our contributions are as follows. We present generalized L1-Tucker decomposition for N-way tensors.

Another straightforward robust reformulation is L1-Tucker [21, 22], which derives by simple substitution of the L2-norm in the Tucker formulation by the more robust L1-norm (not to be confused with sparsity-inducing L1-norm regularization schemes).
