"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.
