A new method of attribute reduction of decision table based on discernibility matrix 一种新的基于区别矩阵的决策表属性约简方法
Method of attribute reduction of decision table based on the information view of rough sets theory 基于粗糙集信息观的决策表属性约简方法
Attributed scattering center comprises more features for sar atr , but because of its high dimensionality , the method of attributed scattering center extraction is more complicated 属性散射中心包含了更丰富的可用于目标分类识别的特征,但同时由于特征参数的维数更高,因此相应的特征提取方法更复杂。
Moreover , a simple effective method of attribute reduction was presented , the main process was to determine the information core , calculate significance of dispensable condition attribute and obtain the relative attribute reduction set 该方法主要包括信息核的求取、可省条件属性的重要性计算和相对属性约简集的确定。
In this strategy , the theory and methods of attribute importance within rough set were applied to define the weight of each feature attribute of the case ; the theory and methods of knowledge reduction was applied to define the index of the case knowledge base 在该策略中,运用粗糙集中属性重要度的理论和方法,确定事例各特征属性的权重,运用知识约简的理论和方法判断事例知识库的索引。
