    I am a graduate student of computer science. I have studied (artificial) neural networks as a technique for machine learning, as part of the standard artificial intelligence course.

    My research supervisor wants me to study cellular neural networks; he is interested in them himself. He has provided me with the 1988 research paper which originated the idea of a CNN, written by Prof. Leon E. Chua, of the University of California at Berkely. However my supervisor, although a recreational computer scientist, is primarily an electrical engineer. So is Prof. Chua.

    In studying the paper, I see no mention of standard neural networks, machine learning or even AI. The material is filled with electronic engineering jargon, which I don't understand. It appears to be related to the non-linear dynamics and chaotic properties of certain electronic oscillators, known as Chua oscillators. I hope that will make sense to some of you. Personally, I am only able to discern the relationship with non-linear science through frequent use of the Lyapunov function.

    I am completely unable to reconcile the material presented with my knowledge of machine learning. Are CNN's totally unrelated with standard (machine learning) neural networks? Are they an AI topic at all? Can they be called a soft computing technique, like standard ANN's? And ultimately, do they fall in the realm of computer science?

    Thanks in advance.

    I always just thought cell phone networks did hand offs. Your cell phone connects to one tower based on the signal strength and monitors other signals at the same time. If it finds a stronger one it asks that tower for a hand off and your call is rerouted to the new tower seamlessly. The process just keeps repeating with towers being chosen constantly. I have a nice program for my G1 that shows on a map what cell tower I'm connected to and a line from me to it. I've noticed it can flip back and forth between towers every few minutes or so.

    I don't see the AI in it, but then again perhaps my understanding of how they work is too dated.


    Pleased to meet you. Hope you guess my name

    Cellular neural networks have ABSOLUTELY nothing to do with cell phone networks - this much is clear to me. Wikipedia says that CNN's are a 'parallel programming paradigm.'

    I think you can see where some confusion might come in based on your post.

    I realize that this may be confusing for some people. However, it is completely unavoidable, since 'cellular neural network' (CNN) is the standard and accepted name for the technology invented by Prof. Chua (which I'm interested in), although it has nothing to do with cell phone networks. To call it by some other name is impossible, since there exists none.
