模式分类器 meaning in Chinese

pattern classifier

According to the requirements to pd pattern auto - recognition , this paper studies systematically the basic theories and realizable methods for auto - recognition of pd gray intensity image : ( 1 ) in the requirement of on - line pd monitoring for transformer , several discharge models are designed and the relevant experiment methods projected . with discharge model tests , a lot of discharge sample data is acquired . on the base of systematical research on recognition for pd gray intensity image , this paper puts forward two kinds of fractal features , the 2nd generalized dimensions of original pd images and fractal dimensions of high gray intensity pd images , and then the relevant extraction methods
针对局部放电模式自动识别的需要，作者系统地研究了局部放电灰度图像自动识别中的基本理论和实现方法： ( 1 )根据变压器局部放电在线监测的要求，设计了放电模型和实验方法，并通过模型实验获得了大量放电样本数据，为构造局部放电灰度图像和采用bpnn进行识别作好准备； ( 2 )研究了局部放电灰度图像的构造方法以及降维构造32 32灰度和矩阵的方法；在用人工神经网络对局部放电进行模式识别时，分析了bp网络的优缺点，对典型bp网络的结构和学习训练算法提出了改进，采用带有偏差单元的递归神经网络作为模式分类器；采用32 32灰度和矩阵进行bpnn识别结果表明这种方法是有效的。
