Estimating Null Numerical Value with Cloud Model in Database
Zhaohong Wang · Jisuanji gongcheng · 2006
To estimate null value in the database is a main task of data-processing,first it gets the cloud models which present the raw nonempty value in the database,then recoves the value with the cloud to replace the null value.The method considers the original data’s distribution sufficiently and can simulate the humans’ behavior,so it can estimate the null value more precisely.
