Sentence examples for operator selectivity from inspiring English sources
It concludes that in a distributed plan in which each operator has a fixed amount of computing resources allocated to it, routing policies that consider operator selectivity, execution cost, and operator load outperforms simpler policies that only consider one or two factors.
We adopt the asynchronous data flow model for our work, which is typical in Data Stream Processing Systems (DSPS), where operators often have dynamic selectivity and are stateful.
The ability to view query execution plans and some of the associated resource and selectivity for operators within the plan is a major tool in the process of physical database design.
To overcome the problem of selectivity and operator-dependent approach to hip viscosupplementation, a clear identification of whether or not the patient is suitable for HA infiltration treatment in the hip is mandatory.
However, DBMSs still lack adequate support for selectivity estimation of query operators for data types embedded in metric spaces.
To ensure efficiency and flexibility related to time selectivity of the channel, hardware operators are shared among all required computations in order to take into account the required treatment of data flow for each channel type.
Performance of Kalon in terms of sensitivity, specificity, and diagnostic selectivity were similar by all operators and field sites (cut-off = 1.1; Table 2).
For all forms of selectivity, we used a receiver-operator characteristic analysis (ROC) to compare firing rate distributions across trial conditions, and a Wilcoxon test to assess the significance of firing rate differences (p < 0.05).
For example, in Eddies the selectivity and the cost of each operator is estimated considering the whole of the data streamed so far [27].
For selectivity indices, we used a receiver-operator characteristic (ROC) analysis to compare firing rate distributions between conditions; selectivity indices were computed only if at least 15 trials were available for each distribution.
