Abstract: A computer-implemented method for image processing includes obtaining, based on a source image including a first biological object, an identity feature and attribute feature used to represent identity information and attribute information of the first biological object. Based on a target image including a second biological object, a context feature used to represent context information of the second biological object is obtained. Based on the identity feature, a fused image of the source image and the target image, the attribute feature, and the context feature is generated, where the fused image includes a fused biological object of a first biological object and the second biological object, identity information and attribute information of the fused biological object is identical to the identity information and the attribute information of the first biological object, and context information of the fused biological object is identical to the context information of the second biological object.

Abstract: This disclosure is related to determining an item push list for a user based on a reinforcement learning model. In one aspect, a method includes obtaining M first item lists that have been predetermined for a first user. Each first item list includes i?1 items. For each first item list, an ith state feature vector is obtained. The ith state feature vector includes a static feature and a dynamic feature. The ith state feature vector is provided as input to the reinforcement machine learning model. The reinforcement model outputs a weight vector including weights of sorting features. A sorting feature vector of each item in a candidate item set corresponding to the first item list is obtained. The sorting feature vector includes feature values of sorting features. M updated item lists are determined for the first item lists based on a score for each item in M candidate item sets.
