| 摘 要： | 基于人的认知特点，提出了一个反映人的主观偏好性的时序相似度模型，并给出估计其偏好系数的锚点方法。该方法基于可视化操作，通过对锚点序列的相似性判断形成锚点约束，构建约束优化问题以求解偏好系数。实例计算表明了模型的有效性。

| Abstract: | Based on some cognition features of human,this paper provides a time series similarity model,which can indicate analyst preference.And a parameters estimation method of this model: ANCHOR is also introduced.Applying this method,an analyst could visually discriminate the similarity of some 'anchor' time series.According to the results of discrimination,an optimal problem computing the preference parameters is constructed.Finally,an instance is present which verified the model. |
