Artificial Intelligence: Sensor Readings and State Inference

What do observations allow the agent to do?

Predict the future
Make decisions
Infer the world state (correct)
Change the world state

What is a characteristic of observations?

They are always numerical
They are always complex
They often come in very different form than the state itself (correct)
They are always in the same form as the state

What is the role of the agent in the context of observations?

To infer the world state (correct)
To change the world state
To make observations
To predict the future
