In the paper, this study is carried out by means of the comparison of the time series. This paper continues previous Works on QSI and studies the noise sensitivity of this index. The noise sensitivity dependes basically on the labelling process. This study is completed with a comparison with other posible labelling. The alternative labelling tecniques are selected kkeping different goals in mind: A better represntativeness of the class marks, a reduced moise sensivity and a similar number of every symbol into which yhe series are translated. We have carried out a detailed study applying different leveles of noise for all this labeling schemes and checking the quality of the obtaines index. |
