Robust and scalable methods for the dynamic mode decomposition
Travis Askham, Peng Zheng, Aleksandr Aravkin +1
The dynamic mode decomposition (DMD) is a broadly applicable dimensionality reduction algorithm that approximates a matrix containing time-series data by the outer product of a mat…
Foundations of gauge and perspective duality
Alexandre Y. Aravkin, James V. Burke, Dmitriy Drusvyatskiy +2
We revisit the foundations of gauge duality and demonstrate that it can be explained using a modern approach to duality based on a perturbation framework. We therefore put gauge du…
Adapting Regularized Low Rank Models for Parallel Architectures
Derek Driggs, Stephen Becker, Aleksandr Aravkin
We introduce a reformulation of regularized low-rank recovery models to take advantage of GPU, multiple CPU, and hybridized architectures. Low-rank recovery often involves nuclear-…
