In child development understanding seems to considerably precede the ability to articulate that understanding. Also development seems to generally move from highly abstract representations (stick men, smily suns) to more concrete adult-like ones.

Another interesting development is the rise of the use of invariant feature

It's a shame that Evolution Robotics weren't able to develop that system further. A logical progression would be to extend the geometric hashing to 3D and eventually 4D, although that would require a stereo camera or some other way of measuring distances to the observed features. Even so that dem

You can get depth information from single camera motion (eg Andrew Davison's MonoSLAM), but this requires an initial size calibration and continuous tracking. If the tracking is lost at any time you need to recalibrate. This makes single camera systems less practical. With a stereo camera the ba

I am interested in identifying barriers to language modeling and how to
overcome them.
I have no doubt that probabilistic models such as NARS and Novamente can
adequately represent human knowledge. Also, I have no doubt they can learn
e.g. relations such as "all frogs are green" from examples
So my question is: what is needed to extend language models to the level of
compound sentences? More training data? Different training data? A new
theory of language acquisition? More hardware? How much?
What is needed is:
