- In goal-based agents, the user provides the input and knows the expected output; thus, it is an example of supervised learning.
- Unlike simple reflex agents that act solely based on current perceptions, goal-based agents consider the future consequences of their actions.
In the realm of artificial intelligence, goal-based agents represent a significant advancement in how machines make decisions and take actions. These agents are designed to achieve specific objectives by evaluating and choosing actions based on their goals. But what exactly are goal-based agents, how do they work, and why are they so important? Let’s explore this fascinating topic in this blog.
What is a goal-based agent?
A goal-based agent is a type of AI system that operates with the primary function of achieving certain predefined goals. Unlike simpler AI models that might follow static rules or immediate responses, goal-based agents are designed to pursue predefined goals with a high degree of flexibility and intelligence. They can plan, reason, and adapt their strategies to achieve their desired outcomes.

How does it work?
Goal identification: The agent identifies its goals based on user input, predefined criteria, or environmental factors. Goals are often specified in a way that allows the agent to understand what needs to be achieved.
Action evaluation: The agent evaluates different actions and their potential consequences to determine which ones are most likely to help achieve the goals. This involves considering factors like resource availability, potential risks, and expected outcomes.
Planning and execution: Once the best actions are identified, the agent creates a plan and executes it. This plan details the steps and sequence of actions needed to reach the goals.
Monitoring and adjustment: As the agent carries out the plan, it monitors progress and makes adjustments as needed. If new information or changes in the environment occur, the agent revises its strategy to stay aligned with its goals.
Applications of goal-based agents
In self-driving cars, goal-based agents are used to navigate routes, avoid obstacles, and reach destinations. The vehicle’s goal might be to safely transport passengers from point A to point B while optimising for factors like time and fuel efficiency. Besides, virtual assistants like Siri or Google Assistant use goal-based strategies to help users complete tasks. For instance, if a user’s goal is to schedule a meeting, the assistant will plan and execute the necessary steps to find a suitable time and send invitations.
In industrial robots, goal-based agents might be used to perform complex tasks like assembling products or managing inventory. The robot’s goals might include optimising production efficiency or minimising errors. In video games, goal-based agents control non-player characters (NPCs) that pursue specific objectives, such as completing missions or competing in challenges. These agents plan and act based on their goals within the game environment.
