New paper on inference/action-selection – comments welcome

This is a paper I wrote for ICFDG that takes some work from my previous life as a roboticist and applies it to Twig (the procedural animation system I’ve been working on).  However, it’s situated in a tradition that the games community, and even the present-day AI community isn’t very familiar with, so much of the paper is an attempt to survey and explain the literature on using combinational logic for inference – why you’d want to do it, why it’s limited, and what you can do to overcome some of the limitations.  And even then, I’m worried that it won’t be transparent to the reader; not because it’s technically difficult, but just because the motivations won’t be clear.  Anyhow, any advice would be welcome.

Final version of AIIDE paper on procedural animation

This is the revised version of the AIIDE paper on Twig, the procedural animation library I’ve been working on.  I’m going to do a longer journal version of it, so suggestions are very welcome.

Another paper

Men are Dogs (and Women too).  This one’s for the AAAI Fall Symposium on Natural Computation.  It’s my latest effort to try to get my intuitions about cognitive architecture onto paper.  There are a bunch of other arguments that I want to fold into it, but it’s already overdue, so they’ll have to wait for the camera ready copy.  Comments and suggestions welcome.

position paper: ai and psychopathology

I’ve just put up the final version of my position paper for the AAAI Symposium on Intelligent Narrative Technologies.  It argues that popular narratives deal at least as much with the ways characters depart from ideal rationality as it deals with actual rational behavior, that we don’t have computational theories of those modes of behavior, and that we could learn a lot by trying to model them.

make love, not war

I was working yesterday on adding fighting behavior to my procedural character animation.  In particular, I wanted the kids to be able to shove one another around.  But due to a bug they kept approaching one another rather than stopping at “shoving distance.”  So they grapple in what looks like a particularly comical make-out session.  Possibly useful, but best saved for the parent characters…

what is anxiety anyway?

I’ve been trying to think about anxiety recently.  I want to argue that anxiety is part of a broader meta-level control system involved in risk assessment.  The obvious scientific response to this would be something along the lines of “well, duh.”  But I’ve had a great deal of difficulty articulating exactly what I mean to my friends.  So I’m writing this overly long post to try to work through it.  I’ll try using two different analogies, but first I’ll try to give some motivating background.
