Abstract: A fleet management system provides a shared trip platform that virtually connects multiple autonomous vehicles (AVs). Multiple AVs, each transporting at least one passenger, are connected in a shared trip. Each of the AVs provides an audio/video stream of the passenger compartment and a current location to a server. The shared trip platform provides a display in each of the AVs showing the current locations of the two AVs in the shared trip. The shared trip platform also transmits the audio/video streams to AVs connected in the shared trip, enabling a video chat between the passengers in the connected AVs.

Abstract: A fleet management system coordinates multiple autonomous vehicles (AVs) to transport a group of passengers from one location to another. A single user can submit a request to the fleet management system to provide a ride for the group, the request specifying the number of passengers and the pickup location. The fleet management system determines a number of AVs to transport the group based on the number passengers, and dispatches this number of AVs to the pickup location. The AVs pick up the passengers at the pickup location, drive the passengers to a destination, and drop the passengers off at the destination.

Abstract: An online system maintains one or more models that determine likelihoods of a user performing various interactions after being presented with a content item. Additionally, the online system receives information identifying interactions by users with content, and generates embeddings for various users based on the interactions by the users with content. When determining whether to present a content item including an objective identifying an interaction to a user, the online system applies a maintained model to determine a likelihood of the user performing the interaction identified by the objective after being presented with the content item. Additionally, the online system determines a similarity of the embedding of the user to embeddings of users who performed the interaction identified by the objective. Based on a combination of the likelihood determined by the model and the similarity, the online system determines whether to present the content item to the user.
