查询词典 open interval

It allows each edge of a graph data set to be with different interval-gap value. For example, given a graph with n edges, the interval-gap concept provides n interval-gap values, Min_Gap and Max_gap, for these edges correspondingly. By incorporating this concept into the graph mining, discovering frequent sub-graph with time constraints can be more effective.

在本论文中提出了区间间隙的概念，主要即是由固定的Min_Gap、Max_gap将之修改调整为弹性的Min_Gap与Max_gap，此区间间隙弹性的地方即在於图形资料集里的任两个节点所串连的边皆会有不同的区间间隙，也就是一个具有n个边的图形里，将会有n个不同的区间间隙值，也就是Min_Gap与Max_gap，这样的作法对於具有时戳性质的图形探勘将更有效益

若两端压力下降突变点前后的均值变化均超过阈值，判定有泄漏并进行定位：计算两端压力数据的近似小波变换系数，初始化搜索区间，从最大尺度N开始在搜索区间内计算对应近似小波变换系数的信号时延值，利用等比关系将尺度N下的时延估计值转换为N-1下时延估计值，以该值更新搜索区间，重复以上过程至尺度为0，以此时延估计值进行定位。

First of all, we introduce some interval methods and propose a new approach to find confidence interval for the slope in homoscedastic measurement error models. The performance of the interval estimation is compared in terms of both coverage probability and its diameter via simulation studies. Second, we suggest two approaches to estimate confidence intervals for the slope and joint confidence regions for both intercept and slope in heteroscedastic measurement error models. Application of these methods are illustrated with real data sets.
