Target factor screening method and device

The invention relates to a target factor screening method and device, and the method comprises the steps: generating a corresponding data set according to a task type, and obtaining the label information corresponding to each factor type in the data set; checking the obtained multiple factor screening methods based on a first screening standard and label information, constructing a qualified factor screening method set, and performing function classification on each factor screening method in the qualified factor screening method set to obtain a different function factor screening method set; combining corresponding factor screening method sets in the different function factor screening method sets based on a second screening standard to generate a plurality of factor screening processes, scoring the plurality of factor screening processes, and determining a target factor screening process according to a scoring result; by adopting the method, each factor screening process can be checked and evaluated, the ra
