Fast and Accurate Dual-Way Streaming PARAFAC2 for Irregular Tensors -- Algorithm and Application

1 code implementation28 May 2023 Jun-Gi Jang, Jeongyoung Lee, Yong-chan Park, U Kang

Although real-time analysis is necessary in the dual-way streaming, static PARAFAC2 decomposition methods fail to efficiently work in this setting since they perform PARAFAC2 decomposition for accumulated tensors whenever new data arrive.

Fast Partial Fourier Transform

no code implementations28 Aug 2020 Yong-chan Park, Jun-Gi Jang, U Kang

In this paper, we propose a fast Partial Fourier Transform (PFT), a careful modification of the Cooley-Tukey algorithm that enables one to specify an arbitrary consecutive range where the coefficients should be computed.
