| Abstract(in English) | To search locally similar regions in DNA sequences is important to analyze DNA sequences because the similar regions are acknowledged to express meaningful information. The locally similar region is called a motif. However, it is difficult to extract the motifs from DNA sequences because of its huge combination number. Thus, exhaustive search for all candidates is not practical. We have already proposed a new method to extract the motifs using chaotic search method. The chaotic search is an approach combining a heuristic algorithm and a chaotic dynamics. The chaotic search method exhibits higher performance than the conventional methods. Then, effects of refractoriness realized in chaotic neurodynamics have a valuable role in finding motifs. In this report, we further investigate the effects of the refractoriness of the chaotic neurodynamics using four patterns of the refractoriness. As a result, we discovered important relationship between strength after a firing and temporal attenuation of the refractoriness. |
