Embodiment 1
[0023] In the financial field, each transaction has transaction time and transaction amount, and the transaction sequence of the same card over a period of time is a time series data set P. Such as figure 1 As shown, suppose there is a transaction time series data set P={(12:10,12),(12:40,7),(13:10,14),(13:20,5),(13:45,6 ),(14:28,19),(15:10,23),(15:20,67),(15:40,11),(15:50,2),(16:20,98), (16:25,15), (17:20,56)}.
[0024] First, suppose that when the time slice length is 1 hour, (12:10,12), (12:40,7) belong to the first group, (13:10,14), (13:20,5), (13 :45,6) belongs to the second group...(17:20,56) belongs to the sixth group.
[0025] Next, calculate the cumulative number of increments (count) and the head (head) and tail (tail) elements of each group, and each group can get a 3-tuple (head, tail, count). The calculation result of each group is as follows figure 2 shown.
[0026] Assume that when querying, the timestamp is 18:00 and the number of time slices is 6, that...
Embodiment 2
[0029] In order to demonstrate the practical beneficial effects of the method of the present invention, we performed a set of experiments. By comparing the method of the present invention with the traditional method when processing the same amount of data, the method of the present invention uses less time than the traditional method to demonstrate the effect of the method of the present invention.
