Scalable, Efficient, and Fair Algorithms for Structured Convex Optimization Problems
… the alternating least squares algorithm for the Tucker decomposition of tensors. In addition, we introduce the Tucker packing problem for computing an approximately optimal core shape for the Tucker decomposition problem. We prove this problem is NP-hard and provide polynomial-time approximation …

Tensor factorization in civil infrastructure systems
… two main tensor factorization techniques namely Tucker decomposition and PARAFAC decomposition are used to reduce the multidimensional NBI data sets into smaller sets that are used as a basis for clustering and prediction. Four applications on the NBI database are discussed in this work. The …

Modern Electronic Structure Theory using Tensor Product States
… theory for excited triplet states. The n-body Tucker ansatz (which is a truncated TPS wavefunction) developed in our group provides a good approximation to the low-lying states of a clusterable spin system. In this approach, a Tucker decomposition is used to obtain local cluster states which …
