The structure of most learning algorithms is pretty simple (eg. linear
models or decision tree ensembles). A linear classifier for text
classification could be simply converted into a python dictionary where the
keys are terms and values are the coefficients (``coef_``) of the linear
classifier - using sparse regularization (L1) helps a lot to keep memory
requirements low.
Decision trees can be translated into a series of if-then-else statements
that can be evaled (if you are brave).
