Lecture THREE.

What is an Agent in artificial intelligence?

• A program that has no interaction with its environment

• A program that can only act upon its environment through actuators

• A program that can only perceive its environment through sensors

• A program that can perceive its environment through sensors and act upon that environment through actuators

What is the performance measure of a rational agent usually chosen by?

• The actuators

• The sensors

• The environment

• The agent designer

Rational Agent should select an actions that minimize its performance measure to do the right thing.

• True

• False

Answer explanation

Rational Agent should select an actions that maximize its performance measure to do the right thing.

What does PEAS stand for in the context of specifying a task environment?

• Performance, Episodic, Actions, Sensors

• Performance measure, Environment, Actuators, Sensors

• Performance, Environment, Actions, Sequential

• Performance, Episodic, Actuators, Sequential

According to PEAS for Automated Taxi driver, What're the Environment ?

• Types of flowers, trees, and plants in street

• Traffic conditions, weather, road conditions, passenger behavior, etc.

• Camera, GPS, speedometer, accelerometer,

• Local restaurants and attractions

According to PEAS for Spam filtering, What're the Performance measure?

• Size, Color, Shape

• Minimize accuracy of detection.

• Precision, Recall and Accuracy

• Temperature, Humidity, Pressure

In the context of environment types, what does 'fully observable' means?

• An agent's sensors can measure all relevant aspects of the environment at each point in time

• An agent's sensors can measure the environment only in certain conditions

• An agent's sensors can only measure some aspects of the environment

• An agent's sensors cannot measure any aspect of the environment

"The next state of the environment is completely specified by the current state and the action"
What's the environment type?

• Episodic

• stochastic

• Deterministic

• Sequential

In Sequential, Agent receives a single percept per episode. The action does not affect future percepts.

• True

• False

Answer explanation

In Episodic, Agent receives a single percept per episode. The action does not affect future percepts.

In Sequential, Agent receives a sequence of percepts. The action affects future percepts

1. .................... : Environment doesn't change unless agent performs an action.

1. 2. .................... : Environment changes even when the agent doesn't do anything.

2. 3. ..................... : Environment agent's performance score changes over time.
