Well, as often occurs with evolutionary learning apps, there is artistry in creating the fitness function... This is something we (try to) deal with in NM/OpenCog via using probabilistic inference to automatically come up with fitness functions for evolutionary procedure learning But the Euphoria

The link from Lukas seems to suggest that applying this technology is something of an art (is that right?): "As a side note, the fickle nature of the evolutionary approach is the primary reason why euphoria isn't middleware; the team at NaturalMotion helps you integrate it. Most often, you hav

If I was paid to get a good animation, I would cheat: I would use -- mixed forward/inverse dynamics instead of pure (forward) simulation, -- motion capture data mining, -- hand-crafted parameterized models instead of generic NNs On Thu, May 1, 2008 at 8:19 PM, Ben Goertzel <[EMAIL PROTECTED]> w

Actually, it seems their technique is tailor-made for imitative learning If you gathered data about how people move in a certain context, using motion capture, then you could use their GA/NN stuff to induce a program that would generate data similar to the motion-captured data. This would then be
