Mining investment is a kind of venture capital, the risk level of which is impacted by various factors. There are still a lot of uncertainty and ambiguity in the process of evaluating on mining investment decision, so it is more suitable to use fuzzy evaluation methods for it. The core of fuzzy evaluation is membership degree transformation. But the existing transformation methods should be questioned,...
The core of fuzzy evaluation on the safety of belt conveying system is membership degree transformation. But the existing transformation methods should be questioned, because redundant data in index membership degree is also used to compute object membership degree, which is not useful for object classification. The new algorithm is: using data mining technology based on entropy to mine knowledge...
The core of performance fuzzy evaluation is membership degree transformation. But the transformation methods should be questioned, because redundant data in index membership degree is also used to compute object membership degree, which is not useful for object classification. The new algorithm is: using data mining technology based on entropy to mine knowledge information about object classification...
In order to realize evaluation of oil storage safety, clear the redundant data in indexes membership which is not useful for goal classification, based on data mining of entropy, mining knowledge information about object classification hidden in every index, affirming the relation of object classification and index membership, eliminating the redundant data in index membership for object classification...
