Query: Denoising the 3-Base Periodicity Walks of DNA Sequences in Gene Finding   A nonlinear Tracking-Differentiator is one-input-two-output system that can
generate smooth approximation of measured signals and get the derivatives of
the signals. The nonlinear tracking-Differentiator is explored to denoise and
generate the derivatives of the walks of the 3-periodicity of DNA sequences. An
improved algorithm for gene finding is presented using the nonlinear
Tracking-Differentiator. The gene finding algorithm employs the 3-base
periodicity of coding region. The 3-base periodicity DNA walks are denoised and
tracked using the nonlinear Tracking-Differentiator. Case studies demonstrate
that the nonlinear Tracking-Differentiator is an effective method to improve
the accuracy of the gene finding algorithm.
