SUO: Re: automating abduction?




o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o

Tom,

I remember the times -- let's not talk about the mores --
and these remarks were relieved against the backdrop of
discussions about "discovery procedures", in particular,
algorithms for "grammar induction" that were envisioned
to be capable of "systematically searching the space of
all possible hypotheses" to arrive at a fitting theory.
Chomsky simply recognized this as Peirce's problem about
"giving a rule to abduction", instead of induction per se.
As experiments on computer and human subjects mounted up,
and rode off in all directions at once, most people, well,
all but the most diehard behaviorists, began to appreciate
just how poverty-stricken the available stimuli actually
were in comparsion to the combinatorial vastness of the
hypothesis spaces in all but the most trivial settings.
I remember being puzzled, along with many others, about
all this, and it was some time before I realized, simply
by taking seriously what I had been reading in Peirce all
along, that Peirce did "give a rule to abduction", and
its name was none other than the "pragmatic maxim".

There's some links to relevant papers on
abduction in computational settings here:
