讲座内容简介：
Title:Rank-One Matrix
Pursuit for Matrix Completion and Its Extension（关于矩阵填充的秩为1的矩阵追踪算法及其扩展）
Abstract:Matrix completion has been studied for about 10
years. I will explain several approaches to complete a matrix, in particular,
the rank-one matrix pursuit algorithm and its economic version in detail. The
algorithm is scaleable, of linear convergence, and has constant storage
complexity.
Extensive numerical
experiments show that our algorithm has the same accurate as the best approach
while it is much efficient. Linear convergence will be explained in more
detail. Then we extend the algorithm to deal with tensor completion.
