I do not understand the relation in LDA and SVD. In my limited understanding
I understand LDA transforms data points in to a coordinate system  where
they can be easily discriminated/classified. SVD on the other hand is used
for dimension reduction, can you help me bridge the gap by providing
something to read on?

Yes, I felt so too, but again did not want to comment on it untill I had the
MapReduce basics related with it.
