Fuzzy Synthetic Evaluation on Safety of Fully Mechanized Mining Faces Based on Entropy Weight

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
Entropy weight is a kind of objective weight. It can be calculated in terms of information entropy which was put forward by Shannon. If entropy weight was applied in the model of fuzzy synthetic evaluation, the subjectivity can be avoided during ascertaining weights.

Output Prediction Model in Fully Mechanized Mining Face Based on Support Vector Machine

2009 Second International Workshop on Knowledge Discovery and Data Mining, 2009
Support Vector Machine is a new machine learning technique developed on the basis of Statistical Learning Theory, which has become the hotspot of machine learning because of its excellent learning performance. Based on analyzing the theory of support vector machine for regression (SVR), a SVR model is established for predicting the output in fully ...
