Abstract: Systems and techniques are disclosed for determining relevant search query autocompletions for presentation to a user that has entered a prefix into a search application interface. A target search space represented as a knowledge graph may be searched to generate a subgraph of nodes representing autocompletion candidates that correspond to the prefix. Further historical and/or interaction data associated with the user and/or other users of the search application may be used to detemir additional autocompletion candidates. A machine-learned model may be trained to score and rank the candidates based on embeddings extracted by the model for the autocompletion candidates. A listing of the autocompletion candidate ordered based on the scores may be presented as autocompletion suggestions to the user.

Abstract: Techniques for a computer-implemented service for virtual product placement in video frames are described. According to some embodiments, a computer-implemented method includes receiving, at a virtual product placement service, a request to place a two-dimensional image of a virtual product into a video, identifying, by a machine learning model of the virtual product placement service, a surface depicted in the video for insertion of the two-dimensional image of the virtual product, inserting, by the virtual product placement service, of the two-dimensional image of the virtual product into one or more frames of the video onto the surface to generate a video including the virtual product, and transmitting the video including the virtual product to a viewer device or a storage location.
