Active Inference World Models
This demonstration shows an embodied agent built with active inference principles performing complex household tasks in the Habitat-Sim environment. The agent locates hidden objects, reasons about their states, tracks beliefs, and executes an 18-step plan to make and serve tea. It jointly reasons about multiple objects and uses semantic priors and negative evidence. The project includes interactive visualizations of the agent's beliefs, policies, and hidden states.
