Study Notes
Artificial Intelligence (AI) - Agent
- An agent is anything that senses the environment using sensors and acts upon that environment through its actuators.
- A sensor receives input from the environment.
- An actuator helps interact with the environment.
- Percept is the perceptual input of an agent at a given moment.
- Percept sequence is the complete history of everything the agent has perceived.
- Agent function (control policy function) is a set of condition-rules based on which an agent can make decision actions.
Applications of Agents
- AI is successfully used in:
- Finance
- Robotics
- Games
- Medicine
- The web
Vacuum Cleaner Agent
- Example: A vacuum cleaner agent's percepts might be location and status (e.g., [A, Dirty]).
- Actions: Left, Right, Suck, NoOp.
- Function Vacuum-Agent([location, status]) returns an action.
- If status is Dirty, then return Suck.
- If location is A, then return Right.
- If location is B, then return Left.
Rational Agent
- Performance measure is an objective criterion (utility function) for assessing an agent's success.
- Performance measures for a vacuum-cleaner agent include amount of dirt cleaned, time taken, electricity consumed, and noise level.
- Self-driving car performance measures include time to destination (minimized), safety, predictability to other agents, and reliability.
- Game-playing agent performance measures include win/loss percentage (maximized), robustness, and unpredictability (to confuse the opponent).
- A rational agent, for each possible percept sequence, selects an action that maximizes its performance measure given the percept sequence evidence. This includes the agent's built-in knowledge.
- Rationality means doing the right thing.
- Rationality involves maximizing expected performance, information gathering, exploration, and learning.
Variables in Python
- Python is case-sensitive.
- Types of variables include string, float, integer, Boolean, complex, list, tuple, set, and dictionary.
- Number variables (integer, float):
- To define:
x = 5,y = 5.5. - Conversion between data types:
x1 = str(x),y2 = bool(y),x2 = complex(x, y). - Arithmetic operations:
print(x + y, x - y, x * y, x / y, x**y, x % y, x // y).
- To define:
- String variables:
- To define:
name = "ali". - Accessing characters:
print(a[5]),print(a[4:12]). - Repeating strings/characters:
print(a*3). - Splitting strings:
print(a.split()). - Partitioning strings:
print(a.partition('')). - Finding characters/words:
print(a.find("artificial")). - Replacing characters:
print(a.replace('a', 'z')). - Counting characters/words:
print(a.count("e")). - Converting case:
print(a.upper()),print(a.lower()),print(a.capitalize()),print(a.title()),print(a.swapcase()).
- To define:
- Boolean variables:
- To define:
a = True,x = False.
- To define:
