LITHOLOGIC IDENTIFICATION OF VOLCANIC ROCKS THROUGH THE APPLICATION OF THE ROUGH SET NEURAL NETWORK SYSTEM
摘要
Abstract
Aiming at the complex lithology of volcanic rocks and the great difficulty in lithologic identification, the lithologic identification of volcanic rocks is conducted through the application of rough set neural network system and log information. First, the log information is optimized and reduced according to the Rough Set. And then a sample set is established by applying the optimized information. Meanwhile the study is conducted by applying the BP neural network based on LM ( Levenberg-Marquardt ) algorithm. The result of the lithologic identification of volcanic rocks through the application of the characteristic parameters and trained BP neural network shows that this method has the advantage of being quick and steady with the relatively high identification accuracy.关键词
