What Are AI Agents: Explore Types, Functions, and Industry Use Cases

Artificial intelligence, or AI, is not a concept that exists in the future but has become a part of technology at present. In recent years, compared to simple machine learning and algorithms, the field of artificial intelligence has advanced to an extent where these systems are eligible for decision-making, problem-solving, and interaction with the human world.

So faced with the given notions, one of the critical elements in the sphere of AI is the so-called AI agent.

But what exactly is meant by the term AI agents? 

AI Agents: The definition and its working model will help enhance the understanding of what the concept is, the different types of those agents, and how it has been implemented in various companies. 

Basic Understanding of an AI Agent 

An AI agent is any designed and intelligent entity able to receive information from its surrounding environment, process it to decide upon the most suitable action, and continue acting in the defined goal. An AI agent can be compared to an assistant or a system that can perform activities on its own without being supervised all the time.

This happens due to the characteristics of AI agents that can work in interacting environments and learn from them, as well as recognize and change with time to maximize their performance. 

These agents can also work at various levels, ranging from simple automated processes to ones that involve decisions. 

Key Characteristics of AI Agents

It then means that AI agents have some relative qualities that distinguish them from regular programs:

Control: direction because of possessing adequate amounts of data as well as freedom from direct guidance.

Perception: A feature that enables the organism to receive information from the environment or within itself from the use of sensors or input instruments.

Extent: Every AI agent can act for itself and take action to fulfill its objectives.

Intelligence: They can understand and change accordingly, in light of any comments made by other parties or any changes that may suit their existence. 

Thus, let’s attempt to clarify the peculiarities of such types of AI agents, their functions, and the spheres where those magnificent creatures are already working.

Types of AI Agents 

AI agents can therefore be categorized in numerous ways depending on their capabilities, sophistication, and operating context. 

Here are the detailed categories of AI agents. 

1. Reactive Agents

Agent types can be divided into several categories, though some of them are as follows: Reactive agents are the most basic type of AI agents. They have no dependence on internal models and deep learning facilities. 

They act according to this plan based on certain programs that are installed in them and from the interaction with the environment after program execution. These agents do not remember what has happened in the past; they do not even identify patterns; they just do what they are programmed to do at the present, given inputs.

Example: A thermostat is a part of an environment or a context and interacts with an environment. Extent: It is even capable of changing temperatures that are read from the environment.

2. Deliberative Agents

Deliberative agents are more advanced. These types of agents can reason, conclude, and then plan what they are going to do next. They consider the environment, goals, and previous experiences and come up with some plan or strategy to accomplish objectives. 

Example: An autonomous vacuum cleaner that navigates around the area moves around the room and plans on how to clean the place systematically. 

3. Hybrid Agents

Unlike the two other types of agents, which are entirely passive-reactive agents and active-deliberative agents, hybrid agents contain both characteristics of both types. They consist of two tiers of decision-making: one is the instant reactive reaction, and the other is more strategic and rational. These agents are thus efficient, adaptive, and versatile. 

Example: Self-driven cars employ hybrid AI agents. They respond to driveways’ turns immediately but can also calculate a route based on numerous factors of the surroundings. 

4. Learning Agents

Learning agents are of a higher A level and have the feature of learning from the environment in which they are located. It even has what is called reactive and adaptable behavior to some extent to moments of stimuli and previous experiences. The use of corresponding types of machine learning, including reinforcement learning and deep learning, makes these agents learn more intricate procedures and become more efficient as time progresses. 

Example: Personal assistants like Siri, Alexa, or Google Assistant. They adapt to your usage and can offer even better recommendations as well as replies. 

5. Collaborative Agents

Collaborative agents act on behalf of the other agents or interact sometimes with humans to achieve the major objectives that they have set for common ends. In this capacity, they synchronize work, share information, and work together in flow in complex environments.
