The output of parallelALS are two matrices U and M whose product is an
approximation of your input matrix.
The matrices are outputed as sequence files with an IntWritable as key
(the index of the row in the matrix) and a VectorWritable as value which
holds the contents of the row vector.

that the output of RowSimilarityJob can be loaded
by the FileItemSimilarity after doing the appropriate parsing. Is that
correct, or is there actually a way to load the raw output of
RowSimilarityJob into FileItemSimilarity?
Thanks.

In order to use ItemSimilarityJob for this purpose, what should be the
input I need to provide? Would it be the output of seq2sparse?
Thanks again.

You're right, my bad. If you don't use RowSimilarityJob directly

Something that i so far don't see happening with MLib. MLib seems to be
old-style Mahout-like rush to become a collection of basic algorithms
rather than coherent foundation. Admittedly, i havent looked very
closely.

I'm also convinced that Spark is a superior platform for executing
distributed ML algorithms. We've had a discussion about a change from
Hadoop to another platform some time ago, but at that point in time it
was not clear which of the upcoming dataflow processing systems (Spark,

Hi,
Mahout's recommenders are based on analyzing interactions between users
and items/movies, e.g. ratings or counts how often the movie was watched.

That is outdated unfortunately. I will send a list of current algorithms

Hi Sergey,
here is the list of algorithms. We're currently in the progress of
reworking our wiki, that's why the documentation is unfortunately
incorrect at the moment. I've added a ticket for this:

Would be great to add this as an example to Mahout's codebase.

Case 1 is fine as is.
For Case 2 I would suggest to simply experiment, try different
similarity measures like euclidean distance or cosine and see what gives
the best results.

Hi Quentin,
Have you checked the log to ensure that you don't get any exceptions
during the computation?
Could you test the job with a tiny example where you can calculate the
result by hand?
Can you share an input file on which this job fails?
