    Abstract: Exemplary embodiments relate to techniques for facilitating a connection between two users in a call by providing an “answering window” when a user calls. When a caller places a call to a callee, the call invitation may remain open for a window of time during which the caller remains available. The callee may opt to answer the call at any time during the window. During the window, the caller may be placed in a lobby and may share audio and/or video. Accepting the call during the answering window may place the callee in the lobby or may directly convert the interaction into an active call. The callee may request that the window can be altered, or may signal their intention to answer the call at a particular time.

    Abstract: Exemplary embodiments relate to techniques for sharing live video while maintaining an asynchronous copy of the video. According to some embodiments, a user begins to record video and shares the video with selected other users. If one of the other users opts to join the original user, the shared video upgrades to a live video conversation. If no one (or only some participants) joins the original user, the recorded video becomes an asynchronous artifact in the users' messaging history. In some embodiments, the live video may be recorded and shared in response to a first user initiating a video call with at least a second user, but receiving no answer. The first user begins to share a live video (which may become an asynchronous artifact). If the second user joins the call while the video is being recorded, the conversation may upgraded to a video conversation.

    Abstract: Exemplary embodiments relate to uses of face detection in video, and especially in video calls. In some embodiments, face detection may be used to center a camera shot by maintaining a face in the center of a screen. The centering may be applied selectively, such as by overriding centering if the user is looking off-screen. The video may also be cropped to better fit a face in a screen, or to allow multiple faces to appear on screen. In some embodiments, emphasizing the face over the background (or parts of the face over the whole face) allows for improvement in video call performance. Moreover, these techniques can be used to bring certain areas of a camera shot into focus while de-emphasizing the background (or vice versa).

    Abstract: Techniques for using user input to tune calls include receiving communication data from a first client device, at a server, directed to a second client device during a call between the first client device and the second client device; forwarding the communication data to the second device; receiving from one of the first client device or the second client device, first user input data; using the first user input data as an input to a call-tuning model; and modifying a call parameter of the call according to output from the call-tuning model in response to the first user input. Other embodiments are described and claimed.

    Abstract: An online system using attributes of users to select content for presentation to the users predicts one or more attributes of users whose attributes are unavailable to the online system. For a user with one or more attributes unavailable to the online system, the online system applies a model to attributes of additional users to predict one or more attributes of the user. Attributes of the additional user use in the prediction may include demographic information and interactions with content by the additional users. The online system may determine an accuracy of the model by using the model to predict attributes for users whose attributes are known to the online system and comparing the predicted attributes to the known attributes. If the model's accuracy is less than a threshold value, the online system discontinues using the model to predict attributes of users.

    Abstract translation: 使用用户属性选择呈现给用户的内容的在线系统预测其属性对在线系统不可用的一个或多个用户的属性。 对于具有在线系统不可用的一个或多个属性的用户，在线系统将模型应用于附加用户的属性以预测用户的一个或多个属性。 预测中附加用户使用的属性可以包括人口统计信息和附加用户与内容的交互。 在线系统可以通过使用模型来预测模型的精度来预测其属性对在线系统已知的用户的属性，并将预测属性与已知属性进行比较。 如果模型的准确度小于阈值，则在线系统将停止使用模型来预测用户的属性。
