Thanks! Is that standard practice or do people typically serialize their
encoders and then load the binaries later?

I am trying vectorize text data for a Naive Bayes classifier that will be
trained in Hadoop and then the corresponding model will be deployed in a
Java app. My basic approach is to tokenize a string of text data using
Lucene and then encode each token using a StaticWordValueEncoder here are

If you have data like this
tech308215054011194110 Limited 3-Box $20 BOGO,
I have looked around for information about this but I still feel unsure
about whether this is possible. I have recently developed a naive bayes
model in sci-kit learn that takes some short text data (along with a few
other categorical features) and develops a classifier model. I would like
to
solution to
this given all that is included in the Vector class or do I need to create
my own method?

So how does the column mean get calculated if the --pcaOffset option is not
specified? I would think you are just doing SVD at that point.

Bottom line, typically one wants something along the lines
ssvd --pca=true -u=false -v=false -us=true ...

okay thanks. It looks like I have that part running so I will go back to
the SSVDCli to finish the rest. Thanks for your help.

Then use the streaming k-means stuff.

to perform clustering?
I am thinking of an example where I have a large table
