Ted Dunning and Ellen Friedman's Time Series Databases has a section on
this with some approaches to geo-encoding:

Yep, rows are not covered in the blog, my mistake. Too bad it has a lot of
uses and can at very least be optimized for output matrix symmetry.

I'm seeing RowMatrix has a columnSimilarities method but I'm
the downsampling is done as LLR is calculated, so
the entire similarity matrix is never actually calculated unless you disable
downsampling.
The primary use is for recommenders but I’ve used it (in the test suite) for
row-wise text token similarity too.

Just got the latest from Github and tried running `mvn test`; is this error
common and do you have any advice on fixing it?
Thanks!

Can you try doing this before running mvn ?

What OS are you using ?

I'm seeing RowMatrix has a columnSimilarities method but I'm not sure I'm
going down a good path to transpose a matrix in order to run that.
