Medical information data intelligent management method and system based on big data

The invention relates to the technical field of medical data management, in particular to a medical information data intelligent management method and system based on big data. The method comprises the following steps: inputting a sign vector of a user into a trained integrated classifier to obtain a label for assisting learning management; wherein the training process of the integrated classifier comprises the following steps: classifying historical sign vectors through an adaboost algorithm to obtain a classification result; determining the individual discrimination rate of the classifier based on the sign vector misclassification condition of a single user and the user misclassification condition of a plurality of users in the classification result; and updating a weight coefficient of a base classifier in the adaboost algorithm based on the individual discrimination rate to obtain a final integrated classifier. According to the embodiment of the invention, the error rate of the traditional base classifier
