Lectures 1 + 2: Intro to AI and Intelligent Agents

A set dedicated to understanding the basics o what artifical intelligence and intelligent agents

agent

an entity that perceives and acts

rational agents

an agent which selects actions that maximizes it expected utility

What are the characteristics needed to make an rational agent

Sensor, Environment, Actions, and Performance

agent function

maps the percept into sequences to action (f: P* → A)

performance measure

how well an agent is going through the sequence of steps to reach it’s goal

rationality

maximally achieving pre-defined goals which maximize expected utility as much as possible

rational acts depend on what factors?

percepts sequence, internal knowledge, actions, performance measures

what dose PEAS stand for

Performance Measures
Environment
Actuators
Sensors

environments

a collections of states and agent is in

utility

an outcome

What is the lesson AI can learn from the brain

memory and simulation are the key to decision making

Who made the first AI
