Abstract
Embodiments of the application provide a method and device for training a cash-return recognition model and a method and device for cash-return recognition, the training method comprises: acquiring first transaction information of a first transaction and a first cash-return label value of the first transaction; calculating a first cash-return predictive value for the first transaction, and a Q-value's label value corresponding to the first transaction information and the first cash-return predictive value; and training a Deep Q-Network (DQN) by adjusting parameters of the DQN such that an absolute value of a difference between a first Q-value's predictive value output by the trained DQN and the Q-value's label value is smaller than that between the first Q-value's predictive value output by the untrained DQN and the Q-value's label value, the first Q-value's predictive value obtained by inputting the first transaction information and the first cash-return predictive value to the DQN.
