Method of rule acquisition in fish disease diagnosis based on fuzzy rough set
Shen-Ming Gu · Computer Engineering and Applications Journal · 2009
Such uncertainties are addressed as randomness of fish diseases diagnosis,fuzziness of diagnostic information and incompleteness of information acquisition.A fuzzy process in diagnosing fish diseases is illustrated firstly,the challenge of which lay in obtaining the matrix.As rough set theory called for no priori knowledge,it is then employed in diagnosing fish diseases.The symptoms of fish diseases fuzzy sets form condition attribute and the decision attribute from disease fuzzy set make up a fuzzy information table.Fuzzy information table attribute reduction and algorithms steps of rule acquisition of fish diseases diagnosis are analyzed.An example is finally demonstrated about the diagnostic process of the rules acquisition of fish diseases so as to provide a new method in fish disease diagnosis.
