| 摘要: |
| 提出了不确定干预分析模型,主要工作包括:(1) 建立了用于多维不确定数据分析的不确定监测点模型(uncertain surveillance);(2) 建立了基于不确定监测点的不确定干预策略及挖掘评价算法;(3) 在真实数据及仿真数据上对所提出的两种算法作了大量实验比较,验证了所提出的干预策略评价优化算法具有较高精度,效率比朴素方法高出3 个数量级,适合在实际系统中处理海量干预评价. |

| Abstract: |
| This study provides models to analyze the intervention over uncertain data. The main contributions include: (1) It establishes a base model named Uncertain Surveillance; (2) It proposes probabilistic intervention strategies over uncertain surveillance with evaluating algorithms; (3) It gives extensive experiments and makes comparisons to show that the proposed model is highly precise and efficient in three order magnitudes of na?ve methods. |
