Components
Perception: AI Agent collects information from the environment through sensors or provided data. Example: a virtual shopping assistant might read a customer’s text query, analyze product images, or check stock availability. The better it perceives, the more accurately it understands what the customer wants.
Reasoning: AI Agent processes the perceived information to make decisions. Example: the shopping assistant might compare different product options, understand the customer’s budget, and decide which item is the best recommendation. This step ensures the agent doesn’t just react but thinks logically.
Memory or Learning: Allows the AI agent to remember important details. Stores past experiences and learns from them to improve future performance. Example: the shopping assistant might recall the customer’s past purchases or preferences, like their size or favorite brands. With memory, the agent can offer more personalized and consistent service.
Planning: AI Agent organizes its actions to reach a goal. Example: the shopping assistant might break a task into steps, such as recommending a product, adding it to the cart, and arranging for delivery. Planning helps it complete tasks efficiently and prepare for any challenges.
Action: AI Agent performs actions. Example:the shopping assistant sends a product recommendation, places an order, or emails a receipt. Action is the final step that turns all the other components into real results.
How an AI Agent Works in 5 steps
Perception: The first step is gathering information from the environment. Perception helps the assistant understand the customer’s needs and the context. Example: the shopping assistant analyzes a customer’s text query like, "I need running shoes under $100," and checks inventory data to see what’s available.
Memory: The second step is using memory to recall important information. Example: the shopping assistant remembers the customer’s shoe size or past purchases, like a preference for specific brands. This allows the assistant to offer personalized recommendations instead of starting from scratch every time.
Reasoning: The third step is where the assistant uses the data and context to make decisions. Example: the shopping assistant considers the customer’s budget, their preference for running shoes, and the available inventory. It then decides which options best match the request and prepares a recommendation.
Planning: The fourth step is organizing the steps needed to meet the customer’s goal. Example: the shopping assistant, select the right product, checks for discounts, and determines the fastest shipping method. Planning ensures the process is efficient and smooth.
Action: The fifth and last step is acting. Example: the shopping assistant shares the product recommendations with the customer, adds the selected item to the cart, or even processes the order.
AI Agent Architecture
The architecture of an AI Agent is built around four key components. Each plays a crucial role in enabling the agent to function effectively:
Agent Core: is the central processing unit. It integrates all functionalities, ensuring the agent processes information, coordinates tasks, and communicates seamlessly between components.
Memory Module: stores and retrieves information, providing the agent with context and continuity. This allows the agent to remember past interactions, learn from them, and improve future responses.
Tools: are external resources or APIs that the agent can use to perform specific tasks. For example, these could include APIs for retrieving data, interacting with users, or executing complex calculations.
Planning Module: analyzes problems and devises strategies to solve them. It helps the agent determine the steps needed to achieve its goals, prioritize actions, and anticipate potential challenges.
These components are interconnected in a feedback loop: Better perception leads to improved reasoning. Richer memory enhances planning. Effective actions provide new data, which feeds back into perception and reasoning cycles.
