Embodiment Construction

[0055] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] refer to figure 1 Shown is the structural principle diagram of the present invention. Input the heart disease diagnosis index according to the defined case representation form, retrieve the most similar case in the historical case database, and give the diagnosis result of the current case through case reuse, and evaluate the result, if not satisfied Correct the case until a satisfactory case result is found, and finally output the diagnostic result and store the case in the historical case library for solving new problems.

[0057] figure 2 As shown, it is a schematic flow chart of the intelligent diagnosis method for heart disease of the present invention. As can be seen from the figure, the specific implementation steps are described in the flow chart:

[0058] Step 1: Define the case representation;

Abstract

The invention discloses a heart disease intelligent diagnostic method based on case reasoning. The heart disease intelligent diagnostic method based on case reasoning is characterized in that: using various check indexes of a patient as a case to conduct searching in a case base, fining out a record which is most similar to the case as a diagnostic result; and meanwhile using water filling theory to obtain an allocation scheme of various characteristic attribute weights of the case, and rejecting redundant attributes according to the attribute weights, and thereby improving accuracy and speed of the heart disease diagnostic result. The heart disease intelligent diagnostic method comprises the following steps: defining a case expression form; constructing a history case set; using the water filling theory to conduct allocation of the characteristic attribute weights; extracting characteristic attributes according to the allocation result of the attribute weights; calculating similarity of cases; reusing the matched cases; and amending the cases. The heart disease intelligent diagnostic method based on case reasoning improves searching strategies of the case reasoning, conducts attribute reduction link through optimal allocation of the characteristic attribute weights of the cases, and ensures diagnosis accuracy and speed.

Description

technical field [0001] The invention relates to an intelligent disease diagnosis method, in particular to an intelligent diagnosis method based on case reasoning for heart disease. technical background [0002] In the medical field, diseases such as heart disease and other high-risk diseases are always threatening people's health. The diagnosis process of such diseases is specific and complicated, and the types of diseases are complex and diverse. In addition, the differences between individual patients bring difficulties to diagnosis. , and my country's high-level medical experts are limited, which makes it impossible for heart disease patients to receive high-level diagnosis and treatment. With the rise and rapid development of artificial intelligence, one of the world's three cutting-edge technologies, its various intelligent technologies have penetrated into various research fields. This also enables medical decision support, including the field of medical diagnosis to r...
