[0059] For the convenience of those skilled in the art to understand the content of the present invention, the following technologies are now explained:
[0060] Matrix completion
[0061]In 2006, Donoho proposed the famous compressed sensing theory in "DONOHO D L. Compressed sensing [J]. Information Theory, IEEE Transactions on, 2006 52(4): 1289-1306", followed by digital cameras, medical imaging, It is widely used in fields such as multimedia hybrid coding, and it is also the source of matrix completion theory. The core idea of compressive sensing theory is: using a small amount of sampled data, the high-dimensional sparse original signal can be accurately restored, that is, the perception of high-dimensional sparse signal can be realized. But in many practical problems such as: text analysis, image repair, recommendation system, etc., the data that needs to be restored is often presented in a matrix. Naturally, the research object of compressed sensing extends from the ...
