I am curious. Do Neural's really learn??
I am proposing a challenge. If a neural cannot learn the
relationship of a mathematical algorithm, then obviously it
cannot even begin to predict the market. So, below is data
which is comprised of the date, the close of SP500, and
an indicator calculated from the last 9 closes. If any
of you really believe in neurals, then I dare you to transfer this data to
your trusty and favorite neural eg., brainmaker, ngo, neuralware, neuroshell
etc. and let it
train, to predict the value of the indicator respective to the date,and close
of the SP. Remember, we are not trying to predict an unknown ( tomorrow's
value, which is a prediction ), we are trying to predict the known value,
which is calculated via a relatively simple mathematical algorithm, from the
last 9 closes.
We are not trying to predict out into the future.
Apply the data below to a neural or whatever.
When you satisfied of the error rate, then apply it to the attached out of
sample
data. Email me the out of sample data back with your program's calculation for
each day of the out of sample data.
MY PREDICTION: NO ONE WILL BE ABLE TO CALCULATE THE
OUT OF SAMPLE DATA'S INDICATOR VALUES WITH INSIGNIFICANT
ERROR'S. AGAIN, REMEMBER THERE IS NO PREDICTING INVOLVED IN
THIS EXERCISE. THINK OF IT AS DECODING A RELATIONSHIP EG.,
1 6 11 16 ....NOW WHAT IS THE VALUE OF THE NEXT NUMBER IN
THE SERIES.. 21. That's exactly what's going on here. My contention is, if
there is a Neural out there can solve for this indicator, then it is
definitely a neural that can LEARN. I haven't found one Neural that can learn
this "algorithm" with insignificant errors. Hope to hear from any of you
Realtraders who haved solved this algorithm.
Below is the training data, and below that is the out of sample data. Good
Luck!
