What Are AI Agents?

An AI agent is a software entity that can perceive its environment, reason about it, and take actions to achieve specific goals without human intervention.

• Key features: Perception, reasoning, action, autonomy, and learning.
• Examples: Virtual assistants (like Siri and Alexa), recommendation systems (like Netflix or Amazon), self-driving vehicles, robotic process automation (RPA) tools, and intelligent chatbots.

• How Do AI Agents Work?
  • Perception: Using sensors, cameras, and data inputs to understand the environment (e.g., AI in autonomous cars using cameras to detect obstacles).
  • Reasoning: AI agents use machine learning algorithms (e.g., reinforcement learning, deep learning) to make decisions and predict outcomes.
  • Decision Making: How AI agents use algorithms to choose optimal actions based on objectives or goals.
  • Learning: Continuous improvement through experience—AI agents adapt and become more efficient over time (e.g., adaptive customer service chatbots).
• Types of AI Agents
  • Reactive Agents: Simple agents that react to specific stimuli but don't retain memory of past interactions (e.g., automated customer service).
  • Deliberative Agents: More complex, these agents use reasoning and planning to make decisions (e.g., self-driving cars planning routes based on traffic and road conditions).
  • Hybrid Agents: Combine both reactive and deliberative approaches for more nuanced behaviors (e.g., AI-powered robots in manufacturing).
