Neural Networks

We've gotten good at using computers to supplement what human brains do poorly (e.g. numerical integration), but brains and computers work very differently. In the old science fiction movies, white-coated actors used to call the huge boxes with whirling tape drives and myriad flashing lights an 'electronic brain,' but even then scientists knew that this was not at all true. Since brains can perform some functions easily that computers can do only with great difficulty - if at all - this begs the question of how we an build computers which are more like brains.

Neural networks are a technology which has just taken off in the last 15 years or so, and is starting to go mainstream. In simple terms, neural nets attempt to crudely imitate the biological processes for recognizing, classifying and responding appropriately to external stimuli. This is sometimes called 'parallel distributed processing.' The most sophisticated artificial neural nets are a long way from even the smallest vertebrate brains, but still show great promise for solving problems which are very difficult to solve robustly with conventional solutions.

I'm interested in exchanging Matlab scripts or related information pertaining to applications of neural nets. My own NN projects so far have been primitive. Among other things, I am interested in applications of NNs to smart spacecraft.

Evolutionary Computation and Artificial Life

I think genetic algorithms - a subset of 'population based methods' are even more fascinating than neural nets, and not only because they hold vast promise for solving all kinds of problems.

Again, we're trying to imitate one of nature's great successes to achieve globally optimized solutions to problems which don't depend on the imagination or cleverness of humans. After all, humans can really only be really creative about items in the immediate consciousness - usually about 7 things for most people. The really cool thing is that great imagination can be built into an algorithm using some simple principles with familiar biological analogies, and this is not limited to what human consciousness can handle. A genetic algorithm can find solutions which require finely balancing a large number of independent variables - something nature does all the time.
