Prof. Dong XIA from Hong Kong University of Sciences and Technology gave a talk entitled ‘High Dimensional Tensor Data Analysis: Statistics and Computation’ at the Faculty of Science and Technology on 19 April, 2019 (Friday). At the seminar, Prof. Dong XIA, shared his latest research results in the fields Statistics and Computation. A tensor is a multi-array of more than 2 dimensions, which can be viewed as a higher order generalization of matrices. He talked several progresses on tensor data analysis involving tensor PCA, tensor sparsification, tensor completion, and discussed computationally efficiency and statistically optimal methods to treat those tensor-related problems.
