In order to run a SSVD in mahout the documents were represented in a tfidf matrix using seq2sparse
(the row-index are the doc-ids and the column-index are the dict-id (word-id)).
The input for SSVD is these tfidf-matrix.
The output of the SSVD job are the matrices U,S,V (transpose).
How i can interprete this output regarding the original tfidf-matrix? Should i multiplice the original one with U, S or V?
What is the conclusion?
Thanks in advance and best regards,
