摘要
在阐述数据挖掘技术的产生背景、过程和一些常用方法的基础上,针对原有BP神经网络算法效率较低、易陷入局部极小等不足,提出了一种改进的BP算法,并对其进行推理和验证;同时将其应用到病人数情况预测中。结果表明,与标准的BP算法相比,改进的BP算法具有更好的精度和更高的效率。
After elaborating the technology of the data mining,including the background,process,and some technologies in common use,this paper presents an improved BP arithmetic aiming at the existed problem of inefficient and easily getting into local minimum.The paper has reasoned it not only in theories,but also in experiments.Finally the paper shows its application to the forecast of the patients' quantity.Compared with the standard BP arithmetic,the improved BP arithmetic is even faster,and more precise.
