AI agents and task environments

The system which perceives the environment and acts accounted as an agent​.

The video introduces different agent types such as:

• Software agent​
• Robotic agent​
• Human agent​

Then we will go through the rational agent, the agent that always chooses the actions which maximises the performance measure (to be most successful), given a percept sequence​ behaviour.

Finally, we cover the “task environment” for an agent.

The first step in designing an AI agent is to specify the task environment. The task environment is comprised of PEAS (Performance measure, Environment, Actuators, Sensors)​.

Discussion:

Reflect upon your understanding of the following:

• What is an agent?​
• When is an agent intelligent?​
