A RK-EMD Method for Similarity Analysis of DNA Sequences

摘要

An Empirical Mode Decomposition (EMD) method based on the Reproducing Kernel (RK) interpolation is presented and applied to similarity analysis of DNA sequences. The reproducing kernel function is used to interpolate the extrema envelopes during the Intrinsic Mode Function (IMF) sifting process. Then we use the classic EMD method and our method to compare the local similarities among DNA sequences respectively. The work verifies our method's suitability and better performance for local similarity analysis of DNA sequences by using the mitochondria of tour different species.
