abstract = "Wind speed fluctuates heavily and affects a smaller
locality than other weather elements. Wind speed is
heavily fluctuated and quite local than other weather
elements. It is difficult to improve the accuracy of
prediction only in a numerical prediction model. An MOS
(Model Output Statistics) technique is used to correct
the systematic errors of the model using a statistical
data analysis. Most previous MOS (Model Output
Statistics) used a linear regression model, but they
are hard to solve nonlinear natures of the weather
prediction. In order to solve the problem of a linear
MOS, a nonlinear compensation technique based on
evolutionary computation is introduced as a new
attempt. We suggest a nonlinear regression method using
GP (Genetic Programming) based symbolic regression to
generate an open-ended nonlinear MOS. The new nonlinear
MOS can express not only nonlinearity much more
extensively by involving all mathematical functions,
including transcendental functions, but also unlimited
orders with a dynamic selection of predictors due to
the flexible tree structure of GP. We evaluate the
accuracy of the estimation by GP based nonlinear MOS
for the three days wind speed prediction for Korean
regions. The training period of 2007- 2009, 2011 year
is used, the data of 2012 year is for verification, and
2013 year is adopted for test. This method is then
compared to the linear MOS and shows superior
results.",
