Tensor completion for estimating
Web3 Jun 2024 · Abstract. We study a noisy tensor completion problem of broad practical interest, namely, the reconstruction of a low-rank tensor from highly incomplete and randomly corrupted observations of its entries. Whereas a variety of prior work has been dedicated to this problem, prior algorithms either are computationally too expensive for … WebIn particular, based on the Tucker decomposition, a convex surrogate for tensor rank, which here we refer to as the sum-of-nuclear-norms (SNN), has been proposed in [23] and serves as a tractable measure of the tensor rank in practical settings. In this work, we focus on low-rank tensor estimation under partial or corrupted observations.
