What about the Moore-Penrose inverse? http://en.wikipedia.org/wiki/Moore-Penrose_pseudoinverse
The pseudo-inverse coincides with the regular inverse when the matrix is non-singular. Moreover, it can be computed using the SVD. Here's a patch for a MapReduce version of the SVD: https://issues.apache.org/jira/browse/MAHOUT-180 Ganesh On Tue, Feb 2, 2010 at 10:11 PM, <[email protected]> wrote: > Hello People, > My name is Abhishek Agrawal.
