World Model

A World Model is a representational system that can maintain internal representations (of environments to enable simulation, prediction, and reasoning about outcomes).

• AKA: Environmental Model, Simulation Model, Internal World Representation.
• Context:
  • It can typically encode Entity Representation with relational structures and dynamic properties.
  • It can typically simulate Future State using predictive mechanisms and causal reasoning.
  • It can typically project Scenario Outcome based on current conditions and potential actions.
  • It can typically adapt Internal Representation through environmental feedback and observational data.
  • It can typically support Decision Making by evaluating predicted consequences of potential actions.
  • ...
  • It can often integrate Multi-Modal Input from sensory systems including visual data, textual data, and auditory data.
  • It can often maintain Temporal Consistency across prediction sequences and simulation steps.
  • It can often facilitate Planning Process through outcome anticipation and goal-directed simulation.
  • It can often enable Counterfactual Reasoning by simulating alternative scenarios and hypothetical conditions.
  • ...
  • It can range from being a Simple World Model to being a Complex World Model, depending on its representational fidelity.
  • It can range from being a Domain-Specific World Model to being a General World Model, depending on its application scope.
  • It can range from being a Static World Model to being a Dynamic World Model, depending on its temporal adaptability.
  • It can range from being a Deterministic World Model to being a Probabilistic World Model, depending on its uncertainty handling.
  • ...
  • It can serve Application Domains including robotics, autonomous systems, scientific modeling, and artificial intelligence.
  • It can employ Modeling Techniques such as physical simulation, statistical prediction, and neural network representation.
  • It can address Model Objectives including navigation, interaction, prediction, and explanation.
