Abstract: Systems, methods and apparatus for processing visual media data are described. One example method includes performing (1102) a conversion between visual media data and a visual media file that includes one or more tracks that store one or more bitstreams of the visual media data; and wherein the visual media data comprises one or more pictures comprising one or more subpictures or one or more slices; wherein the visual media file stores the one or more tracks according to a format rule; and wherein the format rule specifies that a track that includes a sequence of the one or more slices or the one or more subpictures covers a rectangular area of the one or more pictures.

Abstract: Systems, methods and apparatus for encoding or decoding a file format that stores one or more images are described. One example method includes performing a conversion between a visual media file and a bitstream of a visual media data according to a format rule, where the bitstream includes one or more output layer sets and one or more parameter sets that include one or more profile tier level syntax structures, where at least one of the profile tier level syntax structures includes a general constraints information syntax structure, where the format rule specifies that a syntax element is included in a configuration record in the visual media file, and where the syntax element indicates a profile, a tier, or a level to which an output layer set identified by an output layer set index indicated in the configuration record conforms.

Abstract: Systems, methods and apparatus for processing visual media data are described. One example method includes performing a conversion between visual media data and a visual media file that includes one or more tracks that store one or more bitstreams of the visual media data according to a format rule; wherein the visual media file includes a base track that references one or more subpicture tracks, and wherein the format rule specifies an order of non-VCL (video coding layer) NAL (network abstraction layer) units in a sample of the base track in reconstructing a video unit from the sample of the base track and samples in the one or more subpicture tracks.

Abstract: Systems, methods and apparatus for visual media data processing are described. One method includes performing a conversion between a visual media data and a visual media file that stores a bitstream of the visual media data in multiple tracks according to a format rule that specifies that the file-level information includes a syntax element that identifies one or more tracks from the multiple tracks that contain a specific type of sample group that includes operation point information.

Abstract: Embodiments of the present disclosure provide a data processing method and apparatus, an electronic device, and a computer-readable storage medium. In a community division scenario, a community division algorithm is performed in parallel, through a plurality of threads and using fine-grained locks implemented based on atomic operation instructions, on a relationship network to realize community division. Operations such as obtaining a value, accumulation, comparison, and replacement are packaged as instruction level atomic operations by fine-grained locks implemented with atomic operation instructions to give play to inseparability of the atomic operations for guaranteeing that threads having the fine-grained locks would not be interrupted during a process of performing corresponding operations, and the efficiency and stability of community division are thus improved.

Abstract: Provided in the embodiments of the present disclosure are a song list generation method and apparatus, and an electronic device, a computer-readable storage medium, a computer program product and a computer program. The method comprises: acquiring candidate song library information, wherein the candidate song library information comprises feature expressions of candidate songs, and the feature expressions represent song features in a plurality of dimensions; determining a similarity score of at least one candidate song according to the candidate song library information and a target feature expression, wherein the target feature expression is a feature expression of a seed song, and the similarity score represents the similarity between the candidate song and the seed song; and determining a target song on the basis of the similarity score of the candidate song, and generating a recommended song list on the basis of the target song. The similarity between the seed song and the candidate song is evaluated by using the feature expressions which represent the song features in the plurality of dimensions, and therefore a set of target songs which are more consistent with the seed song can be obtained, such that the recommended song list generated on the basis of the target songs has better consistency in the aspects of content, style, etc.

Abstract: Methods and systems for garbage collection and compaction for key-value engines in a data storage and communication system. The method includes determining disk capacity usage of the key-value engine and adjusting a garbage collection percentage threshold and a number of garbage collection threads based on whether the disk capacity usage of the key-value engine meets and/or exceeds predetermined disk capacity usage thresholds. The method may further include performing a periodic compaction process to consolidate one or more expired pages of one or more applications on a log-structured merge (LSM) tree by merging one or more layers into a last layer of the one or more expired pages to reduce data handling during an occurrence of the garbage collection.

Abstract: The present invention relates to a music generation method, apparatus and system, and storage medium. In an embodiment of the present disclosure: obtaining text information, and converting the text information into a corresponding voice audio; obtaining an initial music audio, wherein the initial music audio comprises a music key point, and music characteristics of the initial music audio have a sudden change at the position of an audio key point; and on the basis of the position of the music key point, synthesizing the voice audio and the initial music audio to obtain a target music audio. In the target music audio, the voice audio appears at the position of the music key point of the initial music audio. Thus, a music audio is generated from text information, and the user can customize the content of the text information and customize the initial music audio, so as to achieve the purpose of personalized music customization, thereby overcoming an existing deficiency that personalized music customization cannot be achieved.

Abstract: There are proposed methods, devices, and computer program products for extending a feature space of a data sample. In the method, a global representation is obtained for a feature in a plurality of features of the data sample. A local representation is obtained for the feature based on a classifying criterion for classifying the data sample into one of a plurality of predefined domains. A representation is generated for the feature of the data sample based on the global representation and the local representation. With these implementations, an exclusive feature space may be created for each domain identified by the classifying criterion, which is dedicated to capturing domain-specific knowledge and characteristics.
