Abstract: This application relates to quantum chemistry. The method includes: obtaining training data for a molecular generative model; predicting, if a labeled property value in molecular property label data of a sample molecule in the training data for at least one of M properties is missing, a property value of the sample molecule for at least one property, to obtain molecular property prediction data of the sample molecule; obtaining molecular property tag data of the sample molecule based on the molecular property label data and the molecular property prediction data of the sample molecule; and training the molecular generative model based on the molecular property tag data of the sample molecule, to obtain a trained molecular generative model. This application supports training of the molecular generative model by using the training data without the labeled property value, molecular properties are more abundant and diversity of molecular data is improved.

Abstract: A target dangerous travel scene existing on a target road section is acquired. Reference information corresponding to the target road section is acquired. The reference information is determined according to a detection record corresponding to each of N dangerous travel scenes detected on the target road section within a target time period. N is an integer greater than 1. The detection record corresponds to each dangerous travel scene being used for reflecting time at which the corresponding dangerous travel scene is detected. An associated dangerous travel scene correlated to the target dangerous travel scene from the N dangerous travel scenes is determined according to the reference information. A prompt operation according to the target dangerous travel scene and the associated dangerous travel scene is performed.

Abstract: A video processing method includes obtaining, in response to an interaction operation received on a portion of a first image, an adjustment parameter corresponding to the interaction operation. The adjustment parameter indicates an adjustment range of a display position of one or more pixels corresponding to the portion of the first image based on the interaction operation. The method further includes obtaining a displacement parameter of the one or more pixels in the portion of the first image, the displacement parameter representing a displacement of the one or more pixels between the first image and a second image displayed after the first image. The method also includes adjusting a display position of one or more pixels in the second image based on the adjustment parameter and the displacement parameter, and displaying the second image based on the adjusted display position of the one or more pixels.

Abstract: A virtual object display method is provided. In the method, a virtual object in a virtual scene is displayed. The virtual object is configured to perform a plurality of attribute-affecting actions in the virtual scene. Each of the plurality of attribute-affecting actions includes a plurality of sub-actions. A first action trigger operation from a user is received. The first action trigger operation is associated with a first attribute-affecting action of the plurality of first attribute-affecting actions. One or more animations of the virtual object performing at least one first sub-action is displayed based on an attribute of the first action trigger operation.
