Abstract: Systems and methods directed to improve the responsiveness of an application's UI and improve a user's experience are disclosed. In particular, the systems and methods implement layout and rendering of UI components in a mobile application as two independent steps: layout and mount. During the layout step, attributes related to a layout are identified. For example, during the layout step, a list of UI components in each container, and their respective sizes and positions are identified. The layout result is then used in the mount step to create an actual view hierarchy to be rendered on screen once the component becomes visible. As result of this decoupling of layout operations from the rendering operations, the CPU-intensive measure and layout operations can be moved to the background thread, saving milliseconds.

Abstract: An online system obtains a composite prediction associated with a content item indicating a likelihood that a viewing user of the online system will perform a type of conversion associated with the content item via one or more paths of events leading to the type of conversion. The online system obtains the composite prediction based on a tree data structure describing the path(s) of events. Upon identifying an opportunity to present content to the viewing user, the online system identifies the tree data structure corresponding to the type of conversion from multiple tree data structures maintained in the online system and obtains a composite prediction associated with the content item by evaluating and performing operations associated with nodes of the tree data structure while traversing the nodes. The online system then determines whether to present the content item to the viewing user based on the composite prediction.
