The invention provides a federal learning model training method and device, electronic equipment and a storage medium, and the training method comprises the steps: carrying out the sample alignment with a data provider server; generating a feature code set, and sending the feature number and the public key of the data provider server to the data provider server; dividing a current sample into a training set and a verification set, and obtaining a parameter set of the federated learning model; performing M times of iterative training on the federal learning model according to the training set, the verification set, the parameter set and the feature coding set; and in the process of each iteration training in the M iteration training, if it is judged that the federated learning model meets the early stop condition, controlling the M iteration training to stop early, and obtaining target parameters of the federated learning model obtained by the last iteration training in the M iteration training. Therefore, training can be more efficient, meanwhile, the modeling effect is improved, an early stop strategy is adopted, overfitting of the model is avoided, and meanwhile complexity is reduced.
