中文摘要: 在综合研究了各种算法的基础上,将粗集理论和最小二乘支持向量机算法结合,充分利用了粗集算法能够去除冗余信息,最小二乘支持向量机能够精确加快收敛速的优点。利用具体网络建立一个突出预测机制,并利用本预测机制对矿井瓦斯突出情况进行模拟预测。经过基于MATLAB工具箱的BP神经网络模型的实验对比表明,LS-SVR能加快收敛速度。实验结果表明,基于RS-LS-SVR网络的预测模型可靠,收敛速度快,预测精度高,效果良好。

Abstract:Based on the comprehensive study of the various algorithms, with the rough set theory and the Least Squares Support Vector Regression, taking advantage of rough set method can remove redundant information, Least Squares Support Vector Regression can accurately accelerate the convergence speed advantages. Prominent use of a specific network prediction mechanism, and use this prediction of mine gas outburst mechanism to predict the situation. After based on the MATLAB neural network toolbox BP neural network method of experimental comparison shows that the LS-SVR can speed up the convergence rate. The experimental result reveals that Based on RS-LS-SVR neural network prediction model is reliable, fast convergence and high accuracy, good effect.
