Method for constructing cognitive impairment intelligent prediction

Abstract

The invention provides a method for constructing cognitive impairment intelligent prediction, which comprises the following steps: S1, obtaining original questionnaire data; s2, carrying out data cleaning; s3, carrying out data preprocessing and visualization processing; s4, combining expert knowledge feature screening and intelligent algorithm feature screening to obtain a feature subset; s5, constructing an intelligent cognitive impairment prediction model; s6, verifying the effectiveness of constructing the cognitive disorder intelligent prediction model by adopting ten-fold cross validation; S7, debugging and optimizing the model in combination with expert knowledge; and S8, performing early screening of senile dementia by adopting cognitive impairment intelligent prediction. The method is simple and easy to understand evaluation questions, simple to operate, free of guidance of professional medical staff, and is suitable for an intelligent prediction model which is capable of public self-evaluation and high in prediction accuracy.

Description

technical field [0001] This application relates to the field of Internet technology, and in particular to a method for constructing intelligent prediction of cognitive impairment. Background technique [0002] The onset of cognitive impairment is closely related to the patient's basic situation, living habits, physical condition, medical history, and treatment. It is not entirely clear which factors are highly associated with the onset of cognitive impairment. There are also no effective models capable of predicting risk for cognitive impairment. [0003] Traditional AD screening mostly uses scoring tools such as MMSE and MOCA. Such scales often require medical personnel to guide the assessee and conduct professional quantitative scoring to obtain results. The more complete system questionnaire involves hundreds of items, and it takes a lot of time to fill in, and the final evaluation results will take a long time to calculate. [0004] The intelligent prediction and det...
