Abstract: To present one or more content to users of an online system, the online system identifies a content evaluation pipeline including an order of a plurality of stages having one or more computer models for evaluating a likelihood of user interaction with a content item. The content evaluation pipeline selects a decreasing number of content items, from each stage of the order, according to the order of the stages in the order. The online system identifies a set of candidate modifications to one or more operational parameters of the content evaluation pipeline. For each candidate modification, the online system determines a compute time value and a content selection value. For a given amount of compute time, the online system optimizes the one or more operational parameters based on the determined content time value and the determined content selection value to increase the content selection value of the content evaluation pipeline.

Abstract: Exemplary embodiments relate to the application of coordinated or cooperative effects to a coordinated activity. A coordinated activity protocol is provided for synchronizing interactive effects and experiences across multiple devices. The protocol allows effects to be initiated and coordinated on multiple devices via a real-time communications (RTC) channel. Messages may be exchanged to cooperatively initiate the effect, and (once initiated) generic data may be exchanged via application programming interface (API) calls. According to some embodiments, the coordinated activity is a shared video experience, such as a video conference or shared video-watching experience. According to other embodiments, the coordinated activity relates to other types of experiences, such as single- or multi-player games, shared book reading, communal interactions with a photo album, etc.

Abstract: An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on measured accommodation of user's eye(s). An aberration-adjusted image is an image distorted to correct aberrations that would otherwise occur at a retina of the user due to image light passing through optics of the HMD. The aberration-adjusted image corrects the aberrations of the HMD and “accounts” for the aberrations of the eye so that the resulting retinal image is free of optical aberrations due to the HMD but preserves correct eye optical aberrations that are correlated with a current accommodative state of the eye.

Abstract: Exemplary embodiments relate to the application of media effects, such as visual overlays, sound effects, etc. to a video conversation. A media effect may be applied as a reaction to an occurrence in the conversation, such as in response to an emotional reaction detected by emotion analysis of information associated with the video. Effect application may be controlled through gestures, such as applying different effects with different gestures, or canceling automatic effect application using a gesture. Effects may also be applied in group settings, and may affect multiple users. A real-time data channel may synchronize effect application across multiple participants. When broadcasting a video stream that includes effects, the three channels may be sent to an intermediate server, which stitches the three channels together into a single video stream; the single video stream may then be sent to a broadcast server for distribution to the broadcast recipients.
