Define AI Agent

Define AI Agent refers to explaining an autonomous software system that perceives its environment through sensors, processes information using artificial intelligence algorithms, and executes actions to achieve specific objectives without continuous human oversight. This definition encompasses intelligent entities that operate independently within established parameters, making decisions based on programming, learned experiences, and environmental feedback. AI agents range from simple rule-based systems responding to predetermined conditions to sophisticated machine learning models adapting behavior through reinforcement learning. Key characteristics include decision-making autonomy, environmental reactivity, goal-oriented proactivity, and social interaction capabilities with other agents or humans. Modern applications span chatbots, virtual assistants, autonomous vehicles, and trading algorithms, representing fundamental building blocks of artificial intelligence systems performing tasks traditionally requiring human intelligence and judgment.
