Abstract: According to implementations of the present disclosure, a method, apparatus, device and medium for managing molecular prediction is provided. In the method, an upstream model is obtained from a portion of network layers in a pretrained model, the pretrained model describing an association between a molecular structure and molecular energy.

Abstract: The various implementations described herein include methods and systems for encoding and decoding video. For example, a computing system receives a video bitstream that includes a current block and a syntax element. The current block is encoded using information from a set of reference blocks. The system determines, based on the syntax element, whether the current block is encoded in a compound weighted prediction (CWP) mode. The system decodes the current block using a set of weighted prediction factors when the current block is encoded in the CWP mode. When the current block is not encoded in the CWP mode, the system decodes the current block using an implicit masked blending mode based on a weighted average of reference values associated with the set of reference blocks.

Abstract: A computing system receives a video bitstream that comprises a current block within a current picture and one or more syntax elements. The current block is encoded in a subblock-based motion vector (MV) refinement mode using information from a first reference block and a second reference block. The system applies a MV refinement to generate a refined first MV indicating a first location of the first reference block and a refined second MV indicating a second location of the second reference block. Subsequent to applying the MV refinement, in accordance with a determination that (i) the first location is outside of a first set of reference boundaries and/or (ii) the second location is outside of a second set of reference boundaries, the system decodes the current block using a weighted average of respective values from the first and second locations.
