Abstract: A system comprising a hierarchy of language model-based subsystems has been created to deliver responses to end-users that are within the scope of their queries. A first subsystem, or “conversation tracker,” receives user queries and tracks conversations with users. The conversation tracker keeps track of the conversation state, which comprises the historical context of a conversation a user has with the system. The conversation tracker additionally rephrases user queries to include the relevant historical context identified from the conversation. The conversation tracker also analyzes each rephrased user query and determines a domain (e.g., knowledge or task domain) to which the rephrased query corresponds applies. The conversation tracker forwards the rephrased queries to one of a plurality of additional subsystems, or “task resolvers,” for generation of responses that are ultimately relayed to the user.

Abstract: In a driving policy determining method, for each object, a first target motion trajectory of the object is calculated on a premise that the object does not collide with another object that moves based on an initial motion trajectory. Then, for the ego vehicle, a second target motion trajectory of the ego vehicle is calculated on a premise that the ego vehicle does not collide with another object that moves based on a first target motion trajectory. Then, a driving policy is determined based on the second target motion trajectory of the ego vehicle and a first target motion trajectory of at least one game object. The foregoing operations are repeated until the determined driving policy matches an initial driving policy.
