I think there is a little misunderstanding here.
As I understand Ian, he has estimated a dictionary on some dataset
and wants to use this dictionary to encode some "new" data.

You do not need to estimate anything to get the "model".

What you do want is to "transform" the new data so that it
is coded using the specified dictionary.
I think this is exactly what the sparse encoding method that Olivier
referenced is doing.

Hope I got it right and this clears more things up than confuses.

Cheers,
Andy
