5. data preparation is essential procedure before data mining, and the thesis presents two algorithms for the filling of missing values and the finding of duplicates, two of data problems in data preparation. at first, the thesis uses of rough analysis to predict the missing values with known values to solve the problem of missing values, and the results are with higher accuracy ; then the thesis uses partition data table and quick sort method to find duplicates, which can decrease the searching time for finding
數據預處理是數據挖掘之前的必要準備步驟，針對數據預處理問題中的缺失數據與重復數據的挖掘問題提出兩種演算法，首先針對缺失數據問題，浙江大學博士學位論文利用rough集理論通過對己知數據進行預測實現對缺失數據的填補，達到了一定的預測精度;然後針對重復數據問題，利用數據表分解技術以及快速排序方法實現重復數據的發現，並降低了重復數據的發現時間。 -
