Abstract:
A risk prediction method and apparatus based on reinforcement learning, and a device and a storage medium, which relate to the field of artificial intelligence. The method comprises: receiving a risk prediction request regarding a target subject matter, wherein the risk prediction request comprises a prediction date (S201); acquiring a receipt date of the risk prediction request and target historical data of the target subject matter in N days before the receipt date (S202); performing feature extraction on the target historical data to obtain a target state feature corresponding to each of a plurality of preset feature dimensions (S203); and inputting the target state features into a first risk prediction model to obtain a risk value of the target subject matter on the prediction date (S204), wherein the first risk prediction model is a model that is obtained by means of optimizing a first Actor model on the basis of a first training set, a first Critic model or a second Critic model. By means of the method, the accuracy of risk prediction can be improved, thus facilitating risk decision making.
