One useful solution is to use map-reduce to encode your data as vectors.

That will make training much faster since much of the CPU time is required
only for encoding.

Also, if you would like more help, you really need to tell us more about
the data, the size and the shape for instance.  Without specific questions,
you can't expect to get specific answers.
