Biological vaccine data feature selection method, device, equipment and medium

The invention discloses a biological vaccine data feature selection method, device, equipment and medium, and relates to the technical field of biological vaccine research and development data mining, and the method comprises the steps: 1, carrying out the preprocessing of a high-dimensional biological vaccine data set, calculating the correlation between each feature and a label through the chi-square test, and carrying out the sorting according to the correlation, the top-ranked features of the specified proportion are reserved; 2, dividing the preprocessed biological vaccine data set into a training set and a test set; according to the biological vaccine data feature selection method and device, the equipment and the medium, an algorithm model module, an algorithm iteration module and an algorithm output module are arranged, and a self-adaptive parameter updating strategy is used for replacing fixed parameters of a particle swarm optimization algorithm, so that particles can be searched in a more reasonabl
