Types of knowledge-based agents

Knowledge-based AI agents come in various forms, each designed to address specific needs or environments. Let’s break down the main types of knowledge-based agents and how they excel in different scenarios:
Simple reflex agents
Simple reflex agents are like the "if-this-then-that" experts of AIThey follow a set of predefined rules and react instantly to specific inputs without worrying about previous events. Think of them as reliable, straightforward companions, perfect for predictable and repetitive tasks.
Example: A medical diagnostic system suggests a disease based on symptoms entered australia physiotherapist email list by a doctor, using the rule: "If there is fever, rash, and joint pain, then suggest dengue."
But here’s the catch: Simple reflex agents aren’t exactly flexible. They rely solely on predefined rules; if things get too complex or start changing, these agents can’t adapt. Based on the example above, if the patient has any symptoms other than a fever or rash, the AI agent might not be able to distinguish the condition.
Model-based agents
Model-based agents take AI tools for decision making to the next logical level by building a mental map of their environment . This internal model helps them understand what’s going on, even when they don’t have all the details.
Example: A smart home system maintains an internal representation of the home environment, including factors such as temperature, humidity, and occupancy. When it detects that the temperature exceeds the user's preferred setting, it can adjust the thermostat.
Goal-based agents
These agents focus on achieving specific outcomes by evaluating actions against desired goals. They weigh the various options and decide which is the best path to the correct intent.Imagine an AI Knowledge Base helping a project team meet deadlines: it answers questions based on its prior knowledge and proactively suggests steps to keep the project on track.
Example: A GPS navigation system calculates the best route to a destination taking into account the goal (reaching the location) and factors such as traffic and distance, updating the route dynamically to reach the goal efficiently.
Utility-based agents
Utility-based agents are the AI multitaskers of the workplace . When there’s a lot to do and multiple goals to accomplish, these agents step in to determine the best course of action. They don’t limit themselves to what’s possible, but instead focus on what adds the most value overall.
