Abstract: An anti-shake compensation structure is provided. The anti-shake compensation structure includes an auto-focus module driving a lens to move along a light entering path of the lens. The auto-focus module includes a lens holder holding the lens, a coil adjacent to the lens holder, and a magnet corresponding to the coil. The anti-shake compensation structure further includes an outer frame supporting the lens holder, and a compensation driving unit driving the lens to sway relative to the outer frame along a direction not parallel to the light entering path. The compensation driving unit includes a compensation coil corresponding to the magnet.

Abstract: Rendering graphical user interfaces display query results based on latent intent of users comprises a query network system. The query server stores data for each result of a group of search results, the product data comprising one or more items of metadata that are usable by the one or more computing devices and are not presented with the results for display to a user computing device. The server correlates items of metadata associated with results selected after first query to determine latent intent of the user. The server receives a second query and determines that the second query includes terms related to the first query. The server determines a latent intent of the second query based on the correlation and provides instructions to the user computing device to render a graphical user interface, the graphical user interface comprising the query results.

Abstract: In various embodiments, an optimization engine regenerates items included in an interactive page while the user is interacting with the interactive page. In operation, an optimization engine displays a portion of the interactive page during a viewing session. Subsequently, the optimization engine computes a probability distribution for the viewing session over a set of interests based on model parameters and operations performed by the user during the viewing session. The optimization engine then regenerates items that are included in a second portion of the interactive page based on the probability distribution for the viewing session. The optimization engine displays a least a part of the resulting regenerated interactive page. Advantageously, by regenerating items included in the interactive page based on operations performed by the user during the viewing session, the optimization engine reduces the time required for the user to view an item that piques an interest.
