摘要
Abstract
After mapping the DNA sequence into numerical sequences, the 3-base periodicity behavior of the sequence was recognized as an important property for distinguishing coding regions from non-coding regions. Common mappings were divided into 4 groups and their relationships were discussed. The Parzen window estimation approach was used to obtain a signal-to-noise threshold,by which the classification accuracy and the performance of different mappings could be calculated. Based on the signal to noise curve of the walk sequence, two features of non-oscillation, sensitivity and vibration were proposed to illustrate the efficiency of different mappings.关键词
