Abstract: Split learning is provided to train a composite neural network (CNN) model that is split into first and second submodels, including receiving a noise-laden backpropagation gradient, training the surrogate submodel by optimizing a gradient distance loss, and computing an updated dummy label using the first submodel and the trained surrogate submodel to infer label information of the second submodel. Noise can be added to a label of the second submodel or a shared backpropagation gradient to protect the label information.

Abstract: A method and apparatus for converting a picture into a video, and a device and a storage medium. The method for converting a picture into a video includes: partitioning an original picture to obtain a foreground region and a background region; performing an iterative transformation for visual depth on the background region, and storing an image obtained through each transformation as a picture frame to obtain multiple frames of images; and splicing the multiple frames of images to obtain a target video. The iterative transformation includes at least two transformations for visual depth.

Abstract: A music playing method and apparatus based on user interaction, a device and a storage medium, which relate to the technical field of music videos. The method includes: capturing a target video through a video capturing apparatus; determining an audio processing mode corresponding to a target action when it is identified in the target video that a target object presents the target action; and playing music according to the audio processing mode. The target video is captured by the video capturing apparatus, and when the target object in the target video is identified to generate the target action, the corresponding audio processing mode is determined based on the target action, and music is played according to the audio processing mode.

Abstract: A video capturing method, an apparatus, a device and a storage medium are provided. The method is applied to a terminal device, the terminal device includes a camera, and the method includes: segmenting a to-be-segmented target object to obtain a target segmentation result in response to an input event of selecting the to-be-segmented target object among a plurality of objects presented in an acquisition image of the camera; displaying the target segmentation result; and fusing the target segmentation result, that is adjusted, with a to-be-fused video scene to generate a video in response to a triggering operation for adjusting the target segmentation result.

Abstract: Systems and method directed to generating a stylized image are disclosed. In particular, the method includes, in a first data path, (a) applying first stylization to an input image and (b) applying enlargement to the stylized image from (a). The method also includes, in a second data path, (c) applying segmentation to the input image to identify a face region of the input image and generate a mask image, and (d) applying second stylization to an entirety of the input image and inpainting to the identified face region of the stylized image. Machine-assisted blending is performed based on (1) the stylized image after the enlargement from the first data path, (2) the inpainted image from the second data path, and (3) the mask image, in order to obtain a final stylized image.

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 format rule specifies that first adaptation parameter set network abstraction layer units are disallowed from being simultaneously stored in in the visual media file in (1) any one or both of samples of video coding layer tracks or sample entries of the video coding layer tracks, and (2) samples of non-video coding layer tracks, where the video coding layer tracks are tracks containing video coding layer network abstraction layer units, and where the first adaptation parameter set network abstraction layer units includes luma mapping with chroma scaling parameters for a video stream and scaling list parameters for the video stream.

Abstract: A web authentication system includes a native application to generate at least one safety parameter, a user agent instructed to perform web authentication with safety controls, and a relying party to generate an authentication result. The native application is to deliver the at least one safety parameter to the user agent, obtain the authentication result from the relying party via the user agent, and validate the authentication result with the relying party.

Abstract: The present disclosure describes storage techniques for hybrid transactional and analytical processing. Data captured by a first processing engine may be received. The first processing engine may be configured to perform online transactional processing). Multiple replicas of logical logs generated based on the data may be distributed to a Delta Store by applying a quorum protocol on the multiple replicas. Data in the Delta Store are stored in a row format and are visible to a query for online analytical processing performed by a second processing engine. Data may be flushed from the Delta Store to a Base Store based on one or more predetermined rules. Data in the Base Store are stored in a columnar format and may be accessible by the second processing engine.

Abstract: The present disclosure describes techniques of providing data consistency for hybrid transactional and analytical processing. Logical logs and log serial numbers (LSNs) associated with the logical logs may be generated based on data captured by a first processing engine. The logical logs and the LSNs may be propagated to a storage subsystem configured to be in communication with the first processing engine and a second processing engine. The LSNs and information indicative of LSN schema versions may be stored and distributed by a metadata service. The first processing engine, the second processing engine, the storage subsystem and the metadata service are modularized, and support a LSN mechanism for maintaining data consistency.
