Knowledge Base and Agent Levels

• A knowledge base is a repository of knowledge that an agent uses to reason and make decisions.
• Agents can be viewed at the knowledge level, which focuses on the agent's knowledge and how it is used to make decisions.

KB-Agent Function

• The KB-Agent function returns a set of sentences that can be inferred from the knowledge base.
• The counter 't' in the KB-Agent function indicates the current time step.

Inference Engine and Purpose of 't'

• A forward-chaining inference engine is used in knowledge-based agents.
• The purpose of the counter 't' is to keep track of the current time step in the agent's reasoning process.

Declarative Approach and Make-Percept-Sentence Function

• The declarative approach to building an agent involves specifying what the agent should know and how it should reason with that knowledge.
• The Make-Percept-Sentence function is used to create a sentence that represents the agent's current perception.
