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.

Abstract: A method implemented by a video coding apparatus. The method includes applying a neural network (NN) filter to an unfiltered sample of a video unit to generate a filtered sample, where the NN filter includes an NN filter model generated based on partitioning information of the video unit; and performing a conversion between a video media file and a bitstream based on the filtered sample.

Abstract: Embodiments of the present disclosure provide a method and device for playing a video. The method comprises: in the process of playing a video, displaying a first subtitle in a subtitle component displayed in a playback interface of the video, and playing a first audio corresponding to the first subtitle; in response to a first trigger operation of a user on the subtitle component, displaying a first pop-up window, the first pop-up window being used to switch display of the first subtitle to the second subtitle; in response to a second trigger operation of the user on the first pop-up window, switching to display the second subtitle in the subtitle component, and playing a second audio corresponding to the second subtitle. The video playback method and device provided by the embodiments of the present disclosure can solve the issues that users cannot understand subtitles and audios in the process of watching videos, thereby improving the users' experience.

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: The present disclosure relates to an image attribute classification method, apparatus, electronic device, medium, and program product. The present disclosure enables inputting the image to a feature extraction network to obtain a feature map after feature extraction and N times down-sampling, wherein at least one attribute of the image occupies a second rectangular position area in the feature map after N times down-sampling; calculating a mask function of the at least one attribute of the feature map after N times down-sampling based on the second rectangular position area; obtaining a feature corresponding to the at least one attribute by dot multiplying the feature map after N times down-sampling with the mask function; and inputting the obtained feature corresponding to the at least one attribute to the corresponding attribute classifier for attribute classification.

Abstract: A method is proposed for providing a content page in an application. In the method, a media item is generated, and the media item is associated with respective resources in a resource list that is received from a resource provider. The media item is presented in the application. A content page is caused to be displayed in response to detecting an interaction event of a user of the application with the media item, the content page including respective content items for the respective resources. Therefore, the media item and the content page are generated and displayed in an automatic way for the one or more resource providers without any label work from the resource providers.

Abstract: The present disclosure describes techniques for facilitating a collaborative work environment. The techniques comprise receiving a request from a first client computing device associated with a first user in the plurality of users to establish a communication with a second user in the plurality of users, the request specifying information associated with the communication; generating and transmitting data to a second client computing device associated with the second user for display of a user interface on the second client computing device, wherein the user interface indicates an invite of communication from the first user, and the user interface comprises information about the first user, the information associated with the communication, and selectable interface elements for accepting or declining the invite; and in response to receiving an indication of acceptance by the second user, establishing a communication channel between the first user and the second user.

Abstract: A method implemented by a video coding apparatus includes applying a neural network (NN) filter to an unfiltered sample of a video unit to generate a filtered sample. The NN filter is based on an NN filter model configured to obtain an attention based on a coding parameter input. The method also includes performing a conversion between a video media file and a bitstream based on the filtered sample that was generated.
