Abstract The correlation dimension is an important parameter for describing a chaotic signal. The method of extracting the correlation dimension is deeply researched in this paper. Based on the GP method, an improved algorithm of extracting the correlation dimension is given. The algorithm has the character of little calculating amount, higher accuracy and smaller aimless ability of scaling selection.
