Hinton and Nowlan's results demonstrate it, (c) how Ackley and Littman's results demonstrate it, and (d) how Ackley and Littman's approach compares with that of Hinton and Nowlan. 3. ... important to define them in a more rigorous and quantitative way, and to develop methods to detect and measure them. In other words: How can we decide if an observed system is evolving?...
