  • Publication number: 20240171784
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining watch time loss regions in media content items. In one aspect, features for a video are input into a trained model that is trained to output watch time loss regions. The trained model is trained using labels corresponding to known watch time loss regions in training videos and features of training videos that correspond to the known watch time loss regions. A watch time loss region defines a time window of a video during which a likelihood of a user stopping playback of the video is more than a threshold likelihood. In response to inputting the feature for the first video into the trained model, data regarding watch time loss regions for the video is obtained from the model and provided to an entity involved in providing the video to a user.
