  abstract =     "In this paper, we investigate a method of performing
                 feature transformation on input data in a 1-dimensional
                 space in order to increase the accuracy of classifiers.
                 Through optimized feature transformation, it is
                 possible to create data which generate the models with
                 high accuracy than the original data. We use Genetic
                 Programming (GP) to find a feature transformation
                 function. We proposed evaluation functions using GP and
                 have been successful in finding transformation
                 functions with a high degree of accuracy. On the other
                 hand, where there is a deviation in the number of data
                 items belonging to multiple classes, classes with a
                 large number of data items are more accurate than those
                 that do not. In order to resolve this, referring to
                 existing research, we examined a method of handling the
                 problem of improving accuracy and correcting class
                 imbalanced accuracy from the generated models based on
                 multi-purpose optimization. We then investigated the
                 method of multi-purpose optimization and how to
                 determine the threshold for classification. The results
                 of the investigation were that we could obtain a
                 transformation function that was more accurate and
                 could consider the accuracy of multiple classes
