Hi,
Does map reduce implementation of Pseudo-Inverse of a matrix exist in the
current Mahout framework? What are the various ways to achieve it?
Thanks & Regards,

Hello,
I am seeing from this website
http://theglassicon.com/computing/machine-learning/running-lda-algorithm-mahout
(Mahout 0.5). This website give the complete procedure to get
probabilities of word and topics using LDA. However, these steps donot
work on Mahout 0.7. Can some one give an up
Hi all,
I'm giving one of the distributed matrix factorisation implementations
(code org.apache.mahout.cf.taste.hadoop.als.ParallelALSFactorizationJob) a
try and have a few basic questions. I can't find much documentation about
how to run it so can someone please point me in the right direction?
Your first confusion matrix looks too good to be true, which tells that
there can be a target leak or some other problem in the model.
I wanted to suggest some ModelDissector which you can use for analyzing the
NaiveBayes model, however I just came to know that the ModelDissector in
Mahout does no
Hello Ted,
Thanks for investigating into it.
I would look forward for further analysis and fix in SGD.
I appreciate your efforts in looking into it.
Thanks,

Hi paritosh,
As suggested by you I ran seq2sparse with arguments:-
bin/mahout seq2sparse -i ${user-dir}/fact-seq -o ${user-dir}/fact-vectors
-lnorm -nv -wt tfidf --maxDFSigma 3.0 --maxDFPercent 100 --minSupport 5
but still I am getting the same result..
As suggested by you to use -analyzerNam
Hi I also struggled on this. Here is some code from my classifier, hope you
will find this helpful.
The key point is to use the dictionary you created on your process to train
your model. Which I modified to get the total number of docs.
private void loadTermDictionary(InputStream is) throws IOEx
