粗糙集理论作为处理模糊和不确定知识的一种数学工具,能够在保证分类能力不变的前提下对决策系统进行有效地约简并产生相应的决策规则。较之其他数据处理方法,粗糙集理论的优势在于处理数据时无需任何先验信息,这样得到的处理结果更加贴近客观实际。为此,在棉花病害诊断过程中引入了粗糙集理论,通过对棉花病害信息系统的约简实现了棉花病害的快速诊断,显著提高棉花病害知识发现系统的运行效率,为棉花病害的及时诊断提供一种有效的工具。
粗糙集理論作為處理模糊和不確定知識的一種數學工具,能夠在保證分類能力不變的前提下對決策繫統進行有效地約簡併產生相應的決策規則。較之其他數據處理方法,粗糙集理論的優勢在于處理數據時無需任何先驗信息,這樣得到的處理結果更加貼近客觀實際。為此,在棉花病害診斷過程中引入瞭粗糙集理論,通過對棉花病害信息繫統的約簡實現瞭棉花病害的快速診斷,顯著提高棉花病害知識髮現繫統的運行效率,為棉花病害的及時診斷提供一種有效的工具。

As a mathematical tool of dealing with fuzzy and uncertain knowledge , rough set theory can reduce the deci-sion system effectively and produce corresponding decision rules with guarantee of the unchanged classification ability . Compared with other methods of data processing , the advantage of the rough set theory is to handle data without any priori information ,so as to get the result more closed to the objective reality .Therefore , with rough set theory in the process of cotton disease diagnosis , the reduction of information system about the cotton disease can achieve rapid diagnosis of cotton disease , improve the operation efficiency of knowledge discovery system to cotton disease and provide an effective tool for timely diagnosis of cotton diseases .
