Chaos, Strange Attractors and BrainMaker Plots
|
||
|
||
Take the last 200 years' data on cotton production. Plot a point which
|
||
is one years' production versus the next years'. You get data points
|
||
scattered all over the screen like stars at night. If you were to plot
|
||
A LOT of points (without lines connecting them) you get a shape, like a
|
||
donut. The points seem to fall on or near a circle. This is a Strange
|
||
attractor.
|
||
|
||
In a Normal or Real attractor, you get dense collection of points in the
|
||
middle and spreading out fading out. The price has an equilbrium, the
|
||
production has an equilibrium, represented by the dense collection
|
||
around a single point. A Strange attractor is an attractor for which
|
||
there is not an equilibrium point.
|
||
|
||
There is no math currently that explains the plot of something versus
|
||
something else which produces the donut. The presence of a Strange
|
||
attractor means you're dealing with a chaotic system. A chaotic system
|
||
is a nonlinear feedback system. In the chaotic cotton production
|
||
system, what you learn by seeing the Strange attractor is that there is
|
||
some sort of a feedback mechanism, there is an analytic solution to what
|
||
the system is doing and there is feedback around the analytic solution.
|
||
|
||
You get Strange attractors when you look at the population of foxes over
|
||
the years as it grows and shrinks. This is chaotic, rather than random.
|
||
In a random system, you get points scattered all over with no shape
|
||
whatsoever and there is no underlying mechanism, therefore no way to
|
||
predict anything. In a chaotic system there is an underlying mechanism
|
||
with nonlinearity and feedback. It is believed by some that because
|
||
there is an underlying mechanism analytic approaches can be used to make
|
||
predictions.
|
||
|
||
With BrainMaker Professional you can make plots to find Strange
|
||
attractors. In Netmaker you put cotton price in a column, cotton price
|
||
shifted down by one in another, plot one on the X and one on the Y.
|
||
Plot lots of months worth of data. You will see a donut, a Strange
|
||
attractor, which indicates an underlying mechanism with nonlinearity
|
||
and feedback. If you discover the underlying math that explains this,
|
||
please call us immediately.
