Presently, China's coal mine safety situation is grim, in which a very important reason is lack of safety investment dynamic. Safety investment dynamic analysis and assessment can provide decision basis for effective control and guide. The paper analyzed impact indicators of coal mine safety investment dynamic; established unascertained clustering based coal mine safety investment dynamic assessment...
Application of alternate covering neural network in data mining is given to the classification algorithms, which overcome the continuous iteration and local minimum of traditional neural network algorithms. The calculation speed is high and it is able to adapt to high-dimensional data classification well. Through case study, intuitive geometric significance of alternate covering is used to structure...
Prevention and control of the disastrous accident is the top priority of coal mine production safety. RBF and the combined grey neural network (CGNN) model are established. Combined with cascade-correlation (CC) and RBF-DDA algorithms, gas explosion impacting on coal mine production safety largely is analyzed. The analysis results show that gas explosion accident is caused by many reasons. The relationship...
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...
