"jsdm" is a package for importing data
and using algorithms in the
"Java Sparse Distrbuted Memory" package
by Martin Hassel,
see http://www.nada.kth.se/~xmartin/
"bridges" is a package for importing data from
and using algorithms in
different other packages. These are all very
much to be considered "under construction".
You'll need to download the other packages and
include them in your source path when you compile
your code.
