Pretty remarkable. I wonder how much of the work that went into this natural-language translation program can be generalized to other translation tasks? And would it not be desirable to construct a language translator that can learn on its own, rather than one that has to be spoon-fed all the inference rules for its operation? I guess I have not heard much of this work because a lot of it seems to have a VERY low profile. But if there are results worth pointing to, then please do point to them. > I recall summer work, as an undergrad, in the automated truck assembly >plant that GM Canada runs in Oshawa.

But would it be a good idea to have a system that can learn from example? And about robotics, I note that most present-day models do not have much by way of visual feedback for controlling the motions of their arms. How much progress has there been there? And one may want to have some high-level way of specifying the tasks that they are to perform. One should not need to specify each little detail of their operation, anymore than we consciously specify exactly which muscles to contract, and by how much. >> I was not insisting on any such thing.

I think it does qualify as AI -- it is probably no different from any other type of expert system in that regard. Or are expert systems not really AI? $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Loren Petrich, the Master Blaster: loren@sunlight.llnl.gov Since this nodename is not widely known, you may have to try: loren%sunlight.llnl.gov@star.stanford.edu
