Yvan Paquot at the Universite Libre de Bruxelles in Belgium and a few pals reveal the first incarnation of an exotic new form of computing that exploits a feedback mechanism to perform impressively fast, analogue calculations. The insight that has driven their work is that a nonlinear feedback mechanism is essentially an information processor. It takes a certain input and processes it to generate an output. There’s an important difference between this and other types of computation. The feedback loop is a kind of memory that stores information about the system’s recent history. So this kind processing acts on small segment of the recent past. That’s hugely significant. Many grand challenges in computing, such as speech recognition, depend on processing information from a small window in the recent past.
