Command line arguments are found here: https://cwiki.apache.org/MAHOUT/dimensional-reduction.html I wrote a quick tutorial on how to prepare sparse matrices as input to Mahout SVD here: http://bickson.blogspot.com/2011/02/mahout-svd-matrix-factorization.html
Let me know if you have further questions. 2011/8/29 myn <[email protected]> > i want to study Singular Value Decomposition algorithms; > I also have a book called mahout in action,but i can`t found sth about this > algorithm; > is there someplace introduce how to use the method? > till now DistributedLanczosSolver is not a mapreduce method > org.apache.mahout.math.hadoop.decomposer.DistributedLanczosSolver = svd
