Data processing method and device, equipment and storage medium

The embodiment of the invention discloses a data processing method and device, equipment and a storage medium, and the method comprises the steps: carrying out the initial binning of sample data, and determining an initial binning state corresponding to the sample data after the initial binning; determining an evidence weight of each box of sample data according to a label corresponding to each piece of sample data and the initial box separation state, and determining a box separation state after adjustment and optimization by performing monotone adjustment and optimization on the evidence weight of each box of sample data; and carrying out binning again on the sample data according to the optimized binning state to obtain multi-box target sample data. According to the technical scheme, after the evidence weight of the sample data of each box after initial binning is determined, monotone tuning is carried out on the evidence weight to obtain the optimized evidence weight, binning is carried out on the sample
