报告摘要: Estimating data from an incomplete measurement or observation plays an important role in the area of big data analytic, visual data recovery and network engineering, etc. In this talk, we present two Tensor-Train-factorization-based methods for low rank tensor completion problem. In order to get better performance for real-world data completion, the proposed models make full use of the potential periodicity and inherent correlation properties via temporal regularization. Extensive numerical experiments on internet traffic data, color images, and gray scale video show that the proposed model outperforms many existing state-of-the-art methods.
