Abstract
A system for event prediction using schema networks includes a first antecedent entity state that represents a first entity at a first time; a first consequent entity state that represents the first entity at a second time; a second antecedent entity state that represents a second entity at the first time; and a first schema factor that couples the first and second antecedent entity states to the first consequent entity state; wherein the first schema factor is configured to predict the first consequent entity state from the first and second antecedent entity states.
Claims21
A system comprising one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
- storing a first schema factor network that is configured to generate a prediction of a goal entity state representing an entity at a later time from an antecedent entity state representing an entity at an earlier time;
- performing a backward message passing procedure from the goal entity state to the antecedent entity state through the first schema factor network to determine a cause of a transition from the antecedent entity state to the goal entity state;
- and
- using the cause of the transition to generate a plan comprising a sequence of one or more actions that achieve the goal entity state from the antecedent entity state.
A method comprising:
- storing a first schema factor network that is configured to generate a prediction of a goal entity state representing an entity at a later time from an antecedent entity state representing an entity at an earlier time;
- performing a backward message passing procedure from the goal entity state to the antecedent entity state through the first schema factor network to determine a cause of a transition from the antecedent entity state to the goal entity state;
- and
- using the cause of the transition to generate a plan comprising a sequence of one or more actions that achieve the goal entity state from the antecedent entity state.
One or more non-transitory computer storage media encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:
- storing a first schema network that is configured to generate a prediction of a goal entity state representing an entity at a later time from an antecedent entity state representing an entity at an earlier time;
- performing a backward message passing procedure from the goal entity state to the antecedent entity state through the first schema factor network to determine a cause of a transition from the antecedent entity state to the goal entity state;
- and
- using the cause of the transition to generate a plan comprising a sequence of one or more actions that achieve the goal entity state from the antecedent entity state.
