title: Relationship discovery using Neural networks
body: <p>Suppose I am sampling a number of signals at a fixed rate (say once per second) and extracting some metrics from the signals such as, ratio of one to the other, the rate of change, relative rate of change, etc.<br/>
  I've heard that Neural Networks can be of use in discovering relationships. Is this true?
  <br/>If so, what books/internet resources can I use to learn more about how do do this.
  <br/>The processing is being done is Java, so a Java slant on all your answers would be most appreciated.
  <br/>Thanks</p>
