报告摘要：Tensors are generalizations of higher dimensional matrices， and have many applications in various aspects, such as machine learning, computer vision, signal processing, data mining, and higher-order statistics, etc. Unlike matrices, in tensors, most computational problems including computing ranks are NP-hard. In this talk, we first discuss the ranks of the third-order quaternion tensors and present some inequalities for boundaries. Then we consider QR decomposition of this quaternion tensors and applications in color images and videos processing.
