Abstract: Methods and apparatuses for video encoding/decoding are provided. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode. Then, the processing circuitry determines a usage of a first DMVD process on the current block at least partially based on a second DMVD process not being used on the current block. Further, the processing circuitry reconstructs the current block according to the inter prediction mode with the first DMVD process.

Abstract: Aspects of the disclosure provide a method and an apparatus for video decoding. The apparatus includes processing circuitry receiving prediction information of a plurality of blocks in a current picture from a coded video bitstream. The processing circuitry determines, based on the prediction information, whether at least one of a decoder-side motion vector refinement (DMVR) mode or a bi-directional optical flow (BDOF) mode is allowed for the plurality of blocks. If the DMVR mode or the BDOF mode is allowed for the plurality of blocks, the processing circuitry determines that a plurality of merge with motion vector difference (MMVD) merge flags indicating whether a MMVD mode is applied to the plurality of blocks, respectively, is inferred as false for the plurality of blocks. If the plurality of MMVD merge flags is inferred as false, the processing circuitry reconstructs each block in the plurality of blocks without applying the MMVD mode.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. Processing circuitry decodes prediction information of a block from a coded video bitstream. The prediction information is indicative of a matrix based intra prediction for the block. The processing circuitry determines entries of a vector based on neighboring samples of the block. An entry can be determined based on one or more neighboring samples of the block. The processing circuitry converts the entries into a reduced bit form with a number of bits satisfying a requirement of using a first multiplication tool that processes fewer bits than a second multiplication tool. Then, the processing circuitry multiplies, using the first multiplication tool, the entries of the vector in the reduced bit form with entries of a matrix to calculate a subset of prediction samples of the block, and determines other prediction samples of the block based on the subset.

Abstract: A method of video decoding in a decoder is provided. A first template magnitude of a first transform coefficient in a specific frequency region of the transform block is determined. The first template magnitude is a first single value representing magnitudes of a first local template of the first transform coefficient. A first context model is identified for coding the syntax element of the first transform coefficient, the first context model being shared with at least a second transform coefficient in the specific frequency region of the transform block, a second template magnitude of the second transform coefficient having a second single value that belongs to a first subinterval. A first bin of the syntax element of the first transform coefficient and a second bin of the syntax element of the second transform coefficient is determined, from the coded bits, based on the first context model.

Abstract: Described herein are techniques for using a graph neural network to encode online job postings as embeddings. First, an input graph is defined by processing one or more rules to discover edges that connect nodes in an input graph, where the nodes of the input graph represent job postings or standardized job attributes, and the edges are determined based on analyzing a log of user activity directed to online job postings. Next, a graph neural network (GNN) is trained based on an edge prediction task. Finally, once trained, the GNN is used to derive node embeddings for the nodes (e.g., job postings) of the input graph, and in some instances, new online job postings not represented in the original input graph.
