14 April 2008Latency-information theory and applications: Part I. On the discovery of the time dual for information theory
As part of research conducted on the design of an efficient clutter covariance processor for DARPA's
knowledge aided sensor signal processing expert reasoning (KASSPER) program a time-dual for information
theory was discovered and named latency theory, this theory is discussed in this first of a multi-paper series.
While information theory addresses the design of communication systems, latency theory does the same for
recognition systems. Recognition system is the name given to the time dual of a communication system. A
recognition system uses prior-knowledge about a signal-processor's input to enable the sensing of its output
by a processing-time limited sensor when the fastest possible signal-processor replacement cannot achieve
this task. A processor-coder is the time dual of a source coder. While a source coder replaces a signal-source
to yield a smaller sourced-space in binary digits(bits) units a processor coder replaces a signal-processor to
yield a smaller processing-time in binary operators(bors) units. A sensor coder is the time dual of a channel
coder. While a channel coder identifies the necessary overhead-knowledge for accurate communications a
sensor coder identifies the necessary prior-knowledge for accurate recognitions. In the second of this multipaper
series latency theory is successfully illustrated with real-world knowledge aided radar.
