Hopfield Neural Networks Physical Systems
An auto-associative artificial neural memory is a system which stores mappings of specific input representations to specific output representations. That is to say, a system that "associates" two patterns such that when one is encountered subsequently, the other can be reliably recalled. Kohonen draws an analogy between associative memory and an adaptive filter function . The filter can be viewed as taking an ordered set of input signals, and transforming them into another set of signals---the output of the filter. It is the notion of adaptation, allowing its internal structure to be altered by the transmitted signals, which introduces the concept of memory to the system.
A further refinement in terminology is possible with regard to the associative memory concept, and is ubiquitous in connectionist (neural network) literature in particular. A memory that reproduces its input pattern as output is referred to as autoassociative (i.e. associating patterns with themselves). One that produces output patterns dissimilar to its inputs is termed heteroassociative (i.e. associating patterns with other patterns).
Most associative memory implementations are realized as connectionist networks. Hopfield's collective computation network  serves as an excellent example of an

I dont think your ideas are crazy. In fact what you suggest is something that actually would change the human race forever on this planet. However remember as it stands the reason why humanity has not yet made the jump into the future is because we are held back by our energy issues. Mainly our use of oil as an energy source is holding everything back. Which in turn is also about control by the monetary system we currently have set up as a means for the human race to survive. This includes big banks, wall street, the stock market, and governments. And as we speak our middle class is becoming extinct due to the shift of the global market place as we compete for jobs in cheaper overseas markets. In essences we are becoming a third world country simple because big companies, banks and...

Turning to economic woes, he cited the slide in major stock indexes, the decline in U.S. gross domestic product and Washingtons bailout of banking giant Citigroup as evidence that American dominance of global markets has collapsed.
I was there recently and things are far from good, he said. Whats happened is the collapse of the American dream.
Panarin insisted he didnt wish for a U.S. collapse, but he predicted Russia and China would emerge from the economic turmoil stronger and said the two nations should work together, even to create a new currency to replace the U.S. dollar.
Asked for comment on how the Foreign Ministry views Panarins theories, a spokesman said all questions had to be submitted in writing and no answers were likely before Wednesday.
