Graphical model for tensor factorization by sparse sampling
Graphical model for tensor factorization by sparse sampling arXiv:2510.17886v1 Announce Type: new Abstract: We consider tensor factorizations based on sparse measurements of the tensor components. The measurements are designed in a way that the underlying graph of interactions is a random graph. The setup will be useful in cases where a substantial amount of data…

Generalized Least Squares Kernelized Tensor Factorization
Generalized Least Squares Kernelized Tensor Factorization arXiv:2412.07041v1 Announce Type: new Abstract: Real-world datasets often contain missing or corrupted values. Completing multidimensional tensor-structured data with missing entries is essential for numerous applications. Smoothness-constrained low-rank factorization models have shown superior performance with reduced computational costs. While effective at capturing global and long-range correlations, these models struggle to…
