Distributed Hierarchical SVD in the Hierarchical Tucker Format
Lars Grasedyck, Christian Löbbert
We consider tensors in the Hierarchical Tucker format and suppose the tensor data to be distributed among several compute nodes. We assume the compute nodes to be in a one-to-one c…

Stable ALS Approximation in the TT-Format for Rank-Adaptive Tensor Completion
Lars Grasedyck, Sebastian Krämer
Low rank tensor completion is a highly ill-posed inverse problem, particularly when the data model is not accurate, and some sort of regularization is required in order to solve it…
