description The invention discloses a model training method and a business risk control method and device, and the method comprises the steps: obtaining a training sample; secondly, inputting user data of a target user in the training sample into a to-be-trained prediction model, and determining user service features corresponding to the user data; and then, according to the executed service period of the target user for the target service recorded in the training sample, inputting the user service characteristics into a prediction sub-model matched with the training sample so as to predict a service result corresponding to the target service executed by the target user, and taking the service result as a prediction result. And finally, taking the deviation between the minimum prediction result and the label corresponding to the training sample as an optimization target, and training the prediction model. According to the method, the prediction model can be trained through the training samples of different executed servi
