Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0054] The present invention utilizes this uncertainty to optimize the reliability of historical cases, finally uses the DS reliability combination model to combine them, and gives the final decision result, and combines the quantified expert authority with the reliability combination theory for common use. for decision making. First, quantify the relationship between expert voting results and the certainty of case samples, and give an algorithm for calculating the certainty of case samples; then, give ...

Abstract

The invention provides a treatment plan recommending method based on combination of expert authority and case reliability, and a system. The method comprises the steps of determining k similar historical case samples of a target case, acquiring doctor ballot data and a final treatment plan of each case sample in the k similar historical case samples, calculating doctor ballot accuracies; sequencing the doctor ballot accuracies in the historical case samples, obtaining an authority expert list, and calculating ballot certainty degree according to the authority expert list; calculating a reliability function value according to the k similar historical case samples; multiplying the reliability function value of each historical case sample with the certainty degree, and obtaining the final reliability of the case sample; combining the final reliabilities of the case samples by means of a DS evidence theory, and selecting the treatment plan with highest reliability as a recommended plan. The reliabilities of the historical cases are optimized by means of the process, and finally the DC reliability is combined with the model for generating a final decision result.

Description

technical field [0001] The present invention relates to the related technical fields of machine learning and medical decision-making, in particular, to a method and system for recommending a treatment plan based on the combination of expert authority and case reliability. Background technique [0002] For the recommendation of medical plans, the existing methods mainly combine historical case data and corresponding machine learning algorithms to make the final decision, without directly considering the uncertainty of the plan adopted by the patient in the historical case. Therefore, it is necessary not only to consider the opinions of experts and combine the authority of experts; at the same time, it is also necessary to further pay attention to the differences in the authority of experts in different cases due to differences in experience and knowledge. Based on the above point of view, a feasible idea is: based on a set of historical approximate cases with a given capacity...
