区组设计在改进BP网络样本选取中的应用研究

Application of Block Design on Revised BP Artificial Neural Network

利用多元统计分析中的试验设计思想 ,提出了用区组设计指导样本选取 ,并将之应用于我国西部煤田地质环境评价神经网络建模之中 。

Making use of the test design in multi statistics, this paper puts forward a new rule to select ANN training sample data. It is used to establish the evaluating ANN model of geological environment at coalfield in West China. The result proves that this method is valid.
