METHOD AND DEVICE FOR SMART ANALYSIS OF DATA, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/215671
Kind Code:
A1
Abstract:
A method and device for the smart analysis of data, a computer device and a storage medium. The method for the smart analysis of data comprises: using an obtained public opinion factor and a public opinion index having a time marker as first representation data (S40); acquiring original sample data on the basis of the first representation data and medical data (S50); performing data cleaning on the original sample data to obtain sample data to be processed (S60); performing time-lag processing on the sample data to be processed, so as to obtain time-lag sample data (S70); performing feature expansion processing on the time-lag sample data to obtain target sample data (S80); performing training on the target sample data by using an improved multi-grained cascade random forest algorithm, so as to obtain a target prediction model, the improved multi-grained cascade random forest algorithm comprising a pooling layer configured to retain data features (S90). The method for the smart analysis of data can effectively increase model prediction accuracy and model training efficiency.
