Usually this data has a lot of redundancy, has noise and may miss the information at all in certain percentage of data. In this talk I will discuss the following general problems:

* Reduction process which reduces the storage space of the data
* Denoising the data.
* Predicting the values of the missing data

For the two dimensional data the singular value decomposition (SVD) of an m x n matrix emerged as a very...
