Introduction to Agents

Today we will explore the concept of an agent. Can anyone tell me what they think an agent might be?
Is it a person or a robot that does something?
Great start! An agent is actually anything that can perceive its environment and act upon it. In AI, it refers more to computer programs or systems. Remember, itβs defined as **Agent = Perception + Action**.
So, it has sensors to take in information and actuators to act, right?
Exactly! The sensors help the agent understand whatβs happening in its environment, while the actuators allow it to make changes to that environment.
Can you give an example of an agent?
Sure! Think of a thermostat: it senses the temperature of the room, and if it's too cold, it acts by turning on the heater. Thatβs a simple agent.
To recap, an agent perceives its environment via sensors and acts through actuators. This concept is fundamental in AI, as it helps us understand more complex systems later on.
Formal Definition of Agents

Last time, we introduced agents. Now, how would you express the concept of agents more formally especially in AI?
Maybe by focusing more on the goals they're trying to achieve?
Exactly! An agent is designed to perform specific tasks and achieve goals based on the information it perceives. Formally, it's about Perception + Action.
Does that mean all agents are intelligent?
Not necessarily. While many agents are designed to be intelligent, the definition simply relates to the ability to act based on perceptions. Intelligence varies depending on the complexity of the agent.
So, what makes an agent successful?
Good question! The success of an agent typically depends on how well it perceives and acts in its environment, and this foundation will be crucial when we begin exploring different types of agents.
In conclusion, agents are fundamental to AI as they bridge perception with action, striving toward specific goals. Next time, we will dive into the different types of agents!
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
In Artificial Intelligence, an agent is defined as a system or program that perceives its surroundings through sensors and performs actions to influence that environment. The essential formula representing this concept is Agent = Perception + Action.
Detailed
Detailed Summary
An agent can be defined as anything that perceives its environment via sensors and acts upon this environment through actuators. Particularly in the field of Artificial Intelligence (AI), an agent refers to a computer system or program that interacts intelligently with its surroundings to achieve predefined goals.
Key Points:
- Definition: An agentβs functionalities can be summarized in the equation Agent = Perception + Action. This means that at any moment, an agent receives inputs from its environment (perception) and produces outputs that interact with that environment (action).
- Examples: This concept can be applied across various domains, from simple systems like thermostats to complex systems like autonomous robots.
Understanding what an agent is lays the groundwork for exploring the different types of agents and their roles in AI systems.

An agent is anything that can perceive its environment through sensors and act upon that environment through actuators. In the context of Artificial Intelligence, an agent is typically a computer program or system that interacts intelligently with its surroundings to achieve a specific goal.
Detailed Explanation
An agent is defined as something that can sense its surroundings using sensors (like cameras or microphones) and can take action in that environment using actuators (like motors or screens). In the realm of artificial intelligence, this often refers to software that can autonomously make decisions and perform tasks based on the information it collects from its environment.
Examples & Analogies
Think of a smart thermostat in your home. It senses the current temperature in the room (perception) and adjusts the heating or cooling (action) based on user preferences. The thermostat thus acts like an agent that interacts with the environment of your home to maintain a comfortable temperature.
The Agent Equation

Formally: Agent = Perception + Action
Detailed Explanation
This equation simplifies the concept of an agent by outlining its two primary functions: perception and action. Perception involves gathering data about the environment, while action represents the responses or changes made based on that data. This duality is essential for understanding how agents operate effectively.
Examples & Analogies
Imagine a self-driving car as an agent. Its perception component includes sensors that detect other vehicles, traffic signals, and pedestrians. Based on this information, it takes actions such as accelerating, braking, or turning, making it a fully functional agent in a complex environment.
Functioning of an Agent

At each point in time, an agent receives perceptual inputs from the environment and produces actions that influence that environment.
Detailed Explanation
An agent continuously interacts with its environment. It receives inputs through its sensors, processes this information, and decides how to act. The actions taken by the agent will then affect the environment, creating a feedback loop. This process allows agents to adapt to changes in their environment over time.
Examples & Analogies
Consider a robot that cleans floors. It perceives the dirt and obstacles in its space using sensors. After processing this information, it decides where to move and which areas to clean. Each decision it makes influences how clean the floor will be, demonstrating how agents operate in cycles of perception and action.
