A New Scheme for Nucleotide Sequence Signature Extraction

In this paper, we have proposed a new method that extracts a set of signatures from different nucleotide groups via measuring the distances between the groups. The proposed method not only extracts automatically the signatures of different sizes via constraint relaxation, but also provides the locations of signatures in a sequence while it measures the relative distance between the groups, which provides a convenience for understanding the information on nucleotide. The performance of the proposed method is demonstrated through simulations and analysis
