Optimal High-order Tensor SVD via Tensor-Train Orthogonal Iteration
Yuchen Zhou, Anru R. Zhang, Lili Zheng +1
This paper studies a general framework for high-order tensor SVD. We propose a new computationally efficient algorithm, tensor-train orthogonal iteration (TTOI), that aims to estim…

Testing for high-dimensional network parameters in auto-regressive models
Lili Zheng, Garvesh Raskutti
High-dimensional auto-regressive models provide a natural way to model influence between actors given multi-variate time series data for time intervals. While there has bee…
