Context
Artificial Intelligence is a fascinating field of information technology that permeates many aspects of modern life. Though it may seem complex, we can gain a greater understanding and comfort with AI by exploring its components individually. By learning how these pieces fit together, we can better comprehend and implement AI technologies. This blog introduces the concept of intelligent agents in Artificial Intelligence and delves into the five types of agents in AI. In the context of AI, an “agent” is an independent program or entity that interacts with its environment by perceiving its surroundings through sensors and acting through actuators or effectors. Agents operate in a cycle of perception, thought, and action using their actuators. Examples of agents include:

Analysis
These agents use file contents, keystrokes, and received network packages as sensory input and then act on those inputs, displaying the output on a screen. Humans are natural agents, with eyes, ears, and other organs serving as sensors, while hands, legs, mouths, and other body parts function as actuators. Robotic agents utilise cameras and infrared range finders as sensors and various servos and motors act as actuators. Intelligent agents in AI are autonomous entities that interact with their environment using sensors and actuators to achieve specific goals. These agents can also learn from their environment to enhance their performance over time. Examples of intelligent agents in AI include driverless cars and virtual assistants like Siri .
Key Points
- There are five types of AI agents, each with varying levels of complexity and intelligence—simple reflex agents, model-based reflex agents, goal-based agents, utility-based agents, and learning agents.
- AI agents interact with their environment using sensors to perceive inputs and actuators to perform actions, operating in a cycle of perception, thought, and action to achieve specific goals.
- Examples of intelligent agents include driverless cars, which use sensors and actuators to navigate, and virtual assistants like Siri, which respond to user queries and perform tasks based on learned behaviour.
Actions
Pending intelligence enrichment.
