Parsing
It is necessary to parse these decision trees using some heuristic(s) so that they can be used real time.

parsing the process of ascribing structure to a linear sequence of words or symbols according to the rules of a grammar.

Effecient parsing
At the broadest level, there are three main things we can do improve efficiency:
Don't do twice what you can do once.
Don't do once what you can avoid altogether.
Don't represent distinctions that you don't need.

The problems with parsing become apparent when there is more than one choice of rules to expand in order to create a sentence.

LIMITATIONS OF CONTEXT, SEGMENTATION, AND PARSING
When we see seemingly successful demonstrations of machine learning, in carefully prepared test situations, we must be careful about how we draw more general conclusions.
In certain fields such as language parsing techniques such as chart parsing can exploit constraints in the problem to reduce an exponential complexity problem into a polynomial complexity problem.
In the anagram problem: ...
William Wood at Bolte, Beranek & Newman in Boston conceived a parsing scheme called the Augmented Transition Network.
understanding natural language Just getting a sequence of words into a computer is not enough. Parsing sentences is not enough either.
I'm not sure it's appropriate in the light of the fact that a raster-like parsing technique actually works badly with it.

But, as I write, the painting machine is in the final stages of "training;" learning where everything is, picking up and putting down brushes, dispensing and mixing dyes, parsing the files which AARON will send it.
I think we ought to define what it is about personhood or humanity that we care about (cognition? emotion? perception?...not that these are totally cut and dry parsing problems either) and work from there.
