What are AI Agents

What are AI Agents?

AI agents are autonomous software programs that perceive their environment through sensors and act on it using actuators. An autonomous agent operates independently without human intervention, leveraging advanced technologies such as machine learning, Natural Language Processing (NLP), Large Language Models (LLMs), or Foundation Models (FMs) to execute tasks.
AI agents excel at solving complex problems by decomposing queries, planning task sequences, and employing a reasoning process akin to human thought. They can handle ambiguous questions and utilize various tools—such as APIs, programs, and web searches—to execute tasks and find solutions effectively.

AI is a rational agent, and a human can also be a rational agent, as can an enterprise, a machine, or software itself. An AI agent considers past and present relevant factors to arrive at an optimal, desirable outcome.

Before proceeding, it’s important to understand sensors, effectors, and actuators.

  • Sensor: An electronic device that picks up on environmental changes and sends that information to other electronic devices. Through sensors, an agent can observe its surroundings.
  • Actuators: Parts of machines that turn energy into action. Actuators are limited to the AI system movement and control. Electric motors, gears, rails, and other mechanisms can all function as actuators.
  • Effectors: Devices that have an impact on the environment. Effectors include legs, wheels, arms, fingers, fins, wings, and display screens.

Let’s take a look at some of the features of the AI agents.

Architectural component of AI Agents

Architectural Components of AI Agents

Agentic AI systems have several interconnected components that work together to enable intelligent behavior. Each element plays a crucial role in the overall functioning of the AI system, and they must interact seamlessly to achieve desired outcomes. Let’s explore each of these components in more detail.

Perception Module

  • Sensory Input: This component receives data from various sensors, such as cameras, microphones, tactile sensors, and digital data sources.
  • Feature Extraction: It processes raw data to extract meaningful features that can be used for decision-making.
  • Object Recognition: It identifies objects and entities in the environment using techniques like computer vision, NLP, and ML algorithms for structured data.

Cognitive Module

  • Goal Representation: This module defines the agent’s objectives and desired outcomes.
  • Planning: It generates strategies and plans to achieve the defined goals, considering the agent’s capabilities and environmental constraints.
  • Decision-Making: It selects the most appropriate action based on the current situation, goals, and available options.

Action Module

  • Actuators: Control the agent’s physical or virtual actions through actuators like motors, speakers, or network interfaces.
  • Execution: Implement the selected action to interact with the environment.

Learning Module

  • Reinforcement Learning: Learn from interactions by receiving rewards or penalties for actions.
  • Supervised Learning: Learn from labeled data where correct output is provided for a given input.
  • Unsupervised Learning: Discover patterns and relationships in unlabeled data, including text mining, anomaly detection, and clustering.

Types of AI Agents

To move from the abstract into specifics, let’s examine the actual types of AI agent functions in their hierarchy. AI agents can be categorized based on their capabilities, autonomy, and interaction with their environment. The more deeply a user understands them, the easier it is to select the right AI agent for their purposes. Here is a sampling of well-known AI agents:

Simple Reflex Agent

A simple reflex agent is an AI system that operates solely on the current situation without maintaining an internal model of the world. It perceives its environment and reacts based on predefined condition-action rules, ignoring past perceptions (percept history). These agents function effectively only in fully observable environments, as they rely entirely on current input to decide actions.
Key Characteristics:

  • Condition-Action Rules: Actions are triggered if specific conditions are met.
  • No Memory or Learning: Lacks the ability to store or learn from past experiences.
  • Environment Dependency: Struggles in partially observable environments, often leading to infinite loops unless actions are randomized.

Limitations:

  • Limited Intelligence: Cannot handle complex, dynamic, or unstructured environments.
  • No State Knowledge: Unaware of aspects of the environment not directly perceived.
  • High Complexity: Generating and storing rules can become impractical.
  • Low Adaptability: Requires rule updates for environmental changes.

While simple reflex agents are convenient for straightforward tasks, they are unsuitable for scenarios requiring advanced reasoning, memory, or adaptability.

Goal-Based Agents

Goal-based agents enhance functionality by considering the future impact of their actions. They set goals—such as navigating a maze or playing a game—and make decisions to achieve those goals. Their actions are aimed at reducing the distance to the desired goal, allowing for complex decision-making and planning.

These agents select actions based on how close they are to their goal and can modify their decision-making knowledge, making them flexible. Goal-based agents often rely on search and planning, and their behavior can be easily adjusted.

Goal based agents

Utility-Based Agents

Utility-based agents aim to reach a goal by selecting the optimal course of action. They evaluate various states using a utility function to maximize performance according to a predefined measure. These agents are especially useful in situations with multiple potential actions or outcomes, where they identify the most beneficial path.

Utility-based agents choose actions based on the “utility” or preference of each state. In some cases, simply reaching a goal isn’t enough; factors like cost, speed, and safety are also considered. The utility function quantifies the agent’s “happiness” or satisfaction, guiding it to select actions that maximize expected utility in uncertain environments.

Utility-Based Agents

Autonomous Agents Learning

Learning agents improve their performance based on experience. Starting with basic knowledge, autonomous agents adapt by learning from interactions with their environment, allowing them to optimize strategies over time. These agents are particularly effective in dynamic environments, such as optimizing ad placements based on customer preferences.
A learning agent consists of four key components:

  • Learning Element: Enhances performance by learning from the environment.
  • Critic: Provides feedback on how well the agent is meeting performance standards.
  • Performance Element: Selects actions based on the environment.
  • Problem Generator: Suggests actions to generate new, informative experiences.

Model-Based Reflex Agents

Model-based agents maintain an internal world model that helps them infer hidden elements and fill in missing information. They act based on both their current observations and this internal model.
These AI agents work by matching rules to the current situation, allowing them to handle partially observable environments. They track the internal state, updated by each percept, which depends on the percept history. The state model describes unseen parts of the world.

Updating the internal state requires understanding:

  1. How the world evolves independently of the agent.
  2. How the agent’s actions affect the world.

Model-Based Reflex Agents

Autonomous Learning Agents

Learning agents improve their performance based on experience. Starting with basic knowledge, autonomous agents adapt by learning from interactions with their environment, allowing them to optimize strategies over time. These agents are particularly effective in dynamic environments, such as optimizing ad placements based on customer preferences.

A learning agent consists of four key components:

  • Learning Element: Enhances performance by learning from the environment.
  • Critic: Provides feedback on how well the agent is meeting performance standards.
  • Performance Element: Selects actions based on the environment.
  • Problem Generator: Suggests actions to generate new, informative experiences.

Model-Based Reflex Agents

Multi-Agent System

Multi-agent systems (MAS) consist of multiple autonomous agents or semi-autonomous agents interacting and collaborating in a shared environment to achieve common, individual, or even conflicting goals. These agents coordinate actions and communicate to accomplish objectives, often requiring specialized algorithms to incentivize desired behaviors or enable goal achievement.

A multi-agent system is widely applied in areas like autonomous driving, robotics, automated trading, and gaming. By leveraging multiple agents, MAS enhances efficiency, reduces costs, and increases flexibility in complex systems.

MAS can be categorized as:

  • Homogeneous MAS: Agents with identical capabilities, goals, and behaviors.
  • Heterogeneous MAS: Agents with differing capabilities, goals, and behaviors.

Hierarchical Agents

Hierarchical Agents

Hierarchical agents are structured in a multi-layered system where high-level agents govern the behavior and objectives of lower-level agents, which execute specific tasks. This approach is well-suited for large-scale, complex systems that require task decomposition and management at different levels, providing more organized and efficient decision-making.

Key Characteristics:

  • High-Level Agents: These agents define overarching goals, set constraints, and prioritize tasks. They act as the system’s strategic layer, guiding the entire process based on high-level objectives such as customer demand, production goals, or transportation needs. For example, in a manufacturing system, high-level agents might set targets for production efficiency or resource utilization.
  • Low-Level Agents: These agents are responsible for executing specific tasks, typically within a defined scope or sub-system. They implement the decisions and strategies provided by high-level agents. These tasks can range from simple operations, like managing traffic flow at an intersection, to more complex tasks such as assembling components in a factory. The low-level agents follow a set of predefined rules and protocols designed by high-level agents.
  • Task Decomposition and Coordination: Hierarchical agents break down large, complex tasks into smaller, manageable sub-tasks. These sub-tasks are distributed across lower-level agents for execution, improving the overall efficiency and responsiveness of the system. High-level agents monitor and adjust the task distribution as necessary to achieve optimal results.
  • Scalability and Flexibility: The hierarchical structure of agents allows the system to scale easily by adding more layers or agents at different levels. This flexibility is essential in environments that evolve or require adjustments over time, such as dynamic manufacturing environments or large-scale traffic management systems. Intermediate-level agents can be inserted between the high-level and low-level agents to manage and optimize coordination.
  • Efficiency: By organizing tasks based on agent capabilities and levels of responsibility, hierarchical agents reduce duplication of effort, optimize resource allocation, and improve overall system performance. The system’s complexity is abstracted, enabling faster decision-making processes and better outcomes.
  • Adaptability: Hierarchical agents can adapt to changes in goals, constraints, and environmental conditions. For example, if the demand for a product increases, high-level agents can adjust production targets, which are then communicated to the low-level agents to modify their actions.
  • Autonomous Decision-Making: While high-level agents provide strategic direction, low-level agents make autonomous decisions based on their local environment and task requirements. This enables faster reaction times and reduces the dependency on a centralized decision-maker.

Hierarchical Agents
