摘要：【中文】本发明公开了一种基于时态联动挖掘的时间序列预测方法及其装置。方法用于挖掘类似规则：如果A时间序列大涨(或大跌)，那么k个时间期后B时间序列大涨(或大跌)的概率为x％。方法分为两个阶段。在规则挖掘阶段，针对所有时间序列的每时间期涨跌幅数据，经过简单量化后，统计不同时间序列之间在间隔的一小段时间期内联动大涨或大跌的次数，同时计算出现该联动的支持度和置信度，最后生成联动规则。在规则应用阶段，每时间期根据每只时间序列的涨跌情况进行触发生成，生成的规则分为大涨正面、大涨反面、大跌正面、大跌反面四种类型。方法为时间序列的短期预测提供了一种新方法，改进了传统预测方法的不足，提高了准确性。 【EN】The invention discloses a time sequence prediction method and a time sequence prediction device based on temporal linkage mining. The method is used for mining similar rules: if the a time series is greatly rising (or falling), then the probability of the B time series being greatly rising (or falling) after k time periods is x%. The method is divided into two stages. In the rule mining stage, after simple quantization, the number of times of linkage large rise or large fall between different time sequences in a short time period is counted according to the rise and fall data of each time period of all the time sequences, the support degree and the confidence degree of the linkage are calculated at the same time, and finally the linkage rule is generated. In the rule application stage, triggering generation is carried out in each time period according to the rise and fall conditions of each time sequence, and the generated rules are divided into four types of a large rise front side, a large rise back side, a large fall front side and a large fall back side. The method provides a new method for short-term prediction of the time sequence, overcomes the defects of the traditional prediction method, and improves the accuracy.
