The present disclosure involves methods (200, 300), apparatus, and systems (100, 400) for dynamically determining sensitivity in differential privacy. This can include: identifying a query for aggregate information from a source, wherein the aggregate information is associated with a plurality of users; grouping each piece of information in the source based on an associated user for that piece of information; determining, for each associated user, a primary aggregation, wherein the primary aggregation is a vector representing results to the query sorted by each associated user's contribution to the source; calculating, as a calculated user norm, a user norm for each user's primary aggregation; identifying a subset one or more users whose primary aggregation is greater than the sensitivity associated with the source; and truncating subset one or more users' primary aggregation by a ratio of their associated calculated user norm and the sensitivity.

The present disclosure involves methods (200), apparatus, and systems (100, 300) for multi-layer noise generation in differential privacy (DP). This can include identifying (202) an SQL query; performing (206) an SQL rewrite of the SQL query by replacing at least one process with a DP process; executing (208) the SQL query, and while executing the SQL query injecting noise during the DP process by: generating (210A) random noise; generating (210B, 210C) fixed noise; combining (210D), as combined noise, the random noise and the fixed noise in a weighted sum; and injecting the combined noise during the DP process.

The present disclosure involves methods (200), apparatus, and systems (100, 700) for selection operations to perform a differential privacy (DP) rewrite. This can include: identifying (202) a SQL query; identifying (204) one or more source tables against which the SQL query will be processed and a classification of each source table; generating (206) a parse tree based on the SQL query, the parse tree comprising the one or more source tables, an output table, and at least one operation; searching (210) the parse tree for operations to re-write by: selecting a current branch to search; performing, as an analyzed operation, an analysis of each operation in the current branch starting at the output table and for each operation: determining (212) whether the analyzed operation is an aggregation process that transforms a user-level detailed table (ULDT) into an aggregate table.

The present disclosure provides a method of waking up an application, an electronic device, and a storage medium. The method includes: obtaining target wake-up information (S201); determining, among a plurality of agent objects, a target agent object corresponding to the target wake-up information (S202); and waking up the target agent object (S203).

An interaction control method, a device, and a storage medium are provided. The method includes: acquiring target finger motion information of a user, where the target finger motion information includes a motion speed of a finger and/or a displacement of the finger (S110); determining target state change information of an object to be controlled according to the target finger motion information (S120); and adjusting a state of the object to be controlled according to the target state change information, where different finger motion information corresponds to different state change information (S130). In this way, energy consumption of the device during interaction is reduced, user operations are simplified, and precise control of the object to be controlled is achieved.

The present application provides an earphone and an earphone system, where the earphone includes a sound emitting part, a main body part and an ear hanging part connecting the sound emitting part and the main body part; wherein the sound emitting part includes a first housing, a camera apparatus and a control module, where the first housing is provided with a visual field hole, and the camera apparatus is arranged at the visual field hole,; the control module includes a main board, an image processing unit and a main control unit, where the main board includes a first board body, a second board body and a flexible connecting board which are connected in sequence; the image processing unit is arranged on the first board body; and the main control unit is arranged on the second board body.

Embodiments of the present disclosure provide an interaction control method, an interaction control device, an electronic apparatus and a storage medium, which relate to the technical field of headsets. The method includes: acquiring an interaction state with a terminal apparatus; receiving a voice signal through a microphone; in the case where a bone sound signal is received through a bone sound sensor, determining whether the voice signal is emitted by a wearer at least according to the bone sound signal; and in the case where the voice signal is emitted by the wearer, performing interaction processing with the terminal apparatus based on the interaction state according to the voice signal. Interaction with the terminal apparatus is performed only when it is determined that the voice signal is emitted by the wearer by combining the bone sound signal, thereby solving the problem of a high probability of interaction errors caused by environmental noise.

A method, device and storage medium for content delivery are provided. In the method, a request to deliver a target content to a target object is received. For a content delivery strategy of a plurality of content delivery strategies, at least one group of observed samples are determined based on target features of the target content and the target object, an observed sample comprising reference features of a reference content and a reference object, an indication of whether the content delivery strategy is applied to deliver the reference content and an object response. An effect metric is determined for the content delivery strategy based on the at least one group of observed samples. A target content delivery strategy for delivering the target content to the target object is selected from the plurality of content delivery strategies based on respective effect metrics for the plurality of content delivery strategies.

Embodiments of the present disclosure provide an image processing method, a wearable device (11), an electronic device, and a storage medium. The method includes: determining a target resolution in response to a shooting instruction; and controlling a camera to shoot a first image (a1) with the target resolution for a current environment, where the target resolution is a first resolution or a second resolution, and the first resolution is greater than the second resolution. In the present disclosure, the wearable device (11) may be controlled to shoot images with different resolutions, so that the wearable device (11) may be applied to various scenarios.

According to embodiments of the disclosure, a method, an apparatus, a device, a medium, and a product for display processing are provided. The method includes: determining a plurality of rendering layers to be rendered on a display screen, each rendering layer corresponding to at least a partial interface area in an application interface to be displayed; in response to a number of the plurality of rendering layers being greater than a threshold number, determining a respective priority of each of the plurality of rendering layers, the threshold number indicating an upper limit of a number of rendering layers that may be rendered within a predetermined period; performing rendering on the plurality of rendering layers within the predetermined period based on the respective priority of each of the plurality of rendering layers to obtain a rendering result; and presenting the rendering result on the display screen.
