Researchers from XPENG ROBOTICS propose the Engagement Process (EP), a formal interaction framework that models actions and observations as decoupled event streams on a shared timeline. This approach allows AI agents to explicitly manage complex temporal dynamics in realistic environments, leading to learned time-aware policies that improve responsiveness and adaptiveness compared to traditional synchronous observe-act loops.

Key insights

  • Explicitly modeling time and decoupling action-observation events in the interface enables agents to learn policies that are inherently time-aware and adaptive.
  • The framework promotes richer agent-side internal organization, allowing agents to maintain complex states and manage internal components at different temporal scales.
  • EP facilitates compositional interaction by applying the event-based abstraction recursively, allowing internal subsystems to communicate using the same formal language.
