报告摘要：Classical discrete tensor representations can only represent multidimensional data on meshgrid, limiting their applicability in real-world scenarios beyond meshgrid. To break this limitation, we suggest a new continuous tensor representation as an alternative to the classic discrete tensor representation, providing a unified framework for modeling both meshgrid and off-meshgrid data. Specifically, the suggested representation factorizes the underling multivariate tensor function into simple，structured factors matrices/tensors/functions with interactions between them, which reveals the intrinsic structure behind data. We establish the theoretical foundations for the suggested representation from the complementary perspectives of linear algebra and function approximation. Extensive experiments across image processing, machine learning, scientific computing, and computer graphics demonstrate the expressive power and versatility of the proposed representation compared with state-of-the-art methods.
