  • Abstract
    The paper puts forward a new conversion method that convert original sequence using cosine function, which proves discrete data sequence can improve smoothness by this conversion in theory. And this conversion is used in GM(1,1) model, which is used in example prediction at the end of this paper, which proves the effectiveness of the method of this paper.
