Agent in AI

An agent in AI is a system that observes its environment, makes decisions, and takes actions. It follows a cycle that connects perception with action. Its goal is to achieve a target defined by its designer.

Core Idea

The agent senses the environment, processes the information, and selects the best action. It repeats this loop to improve behavior.

Main Components

1. Environment

The world where the agent operates. It provides inputs and reacts to actions.

2. Sensors

Tools that let the agent read the environment. For software agents, sensors can be text, data, or system states.

3. Actuators

Tools that allow the agent to take actions. For software agents, actuators can be outputs, messages, or API calls.

4. Policy

A rule that guides the agent. It determines actions for each state.

How an AI Agent Works

• Observe the current state.
• Process information.
• Select an action based on the policy.
• Execute the action.
• Receive feedback or new state.

Types of AI Agents

1. Simple Reflex Agents

React to the current state. No memory.

2. Model Based Agents

Use internal state to track the environment.

3. Goal Based Agents

Choose actions that help reach a target.

4. Utility Based Agents

Evaluate outcomes and pick actions with high utility.

5. Learning Agents

Improve behavior through experience.

Where AI Agents Are Used

• Recommendation systems
• Autonomous vehicles
• Game characters
• Automation tools
• Business decision systems

Strengths of AI Agents

• Adaptive behavior
• Continuous interaction
• Support complex tasks

Limitations

• Depend on quality of environment signals
• Need strong policies
• Hard tasks require advanced models
