Abstract: A method for generating behavior with a trait-based planning domain language is disclosed. A world model of a dynamic environment is created. The world model includes data defining a state for the world model. The data defining the state includes data describing objects within the environment. Input to update the state for the world model is received. The input includes data to change the state and data defining a goal for a future state. A machine-learning model is used to generate a planning state from the state for the world model. The planning state includes a plurality of planning domain objects and associated traits. Based on instructions associated with an action, one or more of modifying values within a trait associated with the planning domain object, adding a trait to the planning domain object, or removing a trait from the planning domain object are performed.

Abstract: A method of behavior generation is disclosed. Planning state data in a planning domain language format is received and a state description and an associated action description based on the planning state data are generated. The state description and the associated action description are parsed into a series of tokens for a machine learning encoded state and associated ML encoded action. The series of tokens describe the state and the action. The ML encoded state and ML encoded action is processed with a recurrent neural network to generate an estimate of a value of the state description and the action description. Output of the RNN is taken as input into a neural network to generate a value estimate for a state-action pair. A plan that includes a plurality of sequential actions for an agent is generated. The plurality of sequential actions is chosen based on at least the value estimate.
