Estimation of low-rank tensors via convex optimization

Web5 okt. 2010 · In this paper, we propose three approaches for the estimation of the Tucker decomposition of multi-way arrays ( tensors) from partial observations. All approaches are formulated as convex minimization problems. Therefore, the minimum is guaranteed to be unique. The proposed approaches can automatically estimate the number of factors … WebIn this paper, we address the problem of distributed adaptive estimation of node-specific signals for signal enhancement or noise reduction in wireless sensor networks with multi-sensor nodes. The estimation is performed by a multi-channel Wiener filter ... WebIn this paper, we propose a novel approach for the rank minimization problem, termed rank residual constraint (RRC).
