Grade interpolation in orebody based on support vector regression
-
摘要: 使用與自組織神經網聚類相結合的支持向量回歸機預測模型對礦體體素品位進行插值,并與多邊形法、距離冪次反比法、克里格法進行對比驗證.結果表明,該預測模型進行品位插值具備很好的可行性和可靠性.Abstract: The method of support vector regression (SVR) in combination with self organization feature mapping (SOFM) network was selected for grade interpolation in orebody, and was compared to the Thiessen polygons method, the distance power inverse ratio method and the Kriging method. The result shows that the prediction model of SVR is feasible and reliable for grade estimation.
