PP: Tripoles: A new class of relationships in time series data

Problem:

?? mining relationships in time series data

traditional methods: discover pair-wise relationships.

Introduction:

Challenge: discovery of complex patterns of relationships between individual time-series. ?? what does this mean?

A common type of relationship in time series data is pairs of time-series with strong Pearson correlations. 

In this paper, we define a novel relationship across three time series

tripole: a group of three time-series, one root node/ two leaf nodes.

how to find non-trivial relationships: tripole patterns

需要思考清楚，这个tripole pattern使用于什么情境下的time series data, 比如他可以适用于交通数据transportation data/ sea level pressure data 都和区域有关，那如果对于天气，生产，消费的time series关系是否适用，需要认真思考一下。

Note that a tripole is interesting only if correlation ofT0 withT1+2 is much stronger than correlation of T0 with T1 or T2 individually。

这种tripole现象，以期并没有进行系统的研究，但是我奇怪为什么要衡量T0 and T1+T2的相关性，这种
