A more thorough explanation:

Artificial Intelligence (AI) is a technology that allows machines to learn from data and perform tasks without human intervention. It involves the use of algorithms and machine learning to make predictions and decisions based on existing data sets. According to the United States Code, AI is defined as:

• Any artificial system that can perform tasks without human oversight, or that can learn from experience and improve performance when exposed to data sets.
• An artificial system that can solve tasks requiring human-like perception, cognition, planning, learning, communication, or physical action.
• An artificial system designed to think or act like a human, including cognitive architectures and neural networks.
• A set of techniques, including machine learning, that is designed to approximate a cognitive task.
• An artificial system designed to act rationally, including an intelligent software agent or embodied robot that achieves goals using perception, planning, reasoning, learning, communicating, decision making, and acting.

Examples of AI include:

• Virtual personal assistants like Siri and Alexa that can understand and respond to voice commands.
• Self-driving cars that use sensors and algorithms to navigate roads and avoid obstacles.
• Fraud detection systems that use machine learning to identify patterns of fraudulent behavior.
• Recommendation systems used by online retailers and streaming services to suggest products and content based on a user's past behavior.

These examples illustrate how AI can be used to perform tasks that would normally require human intelligence and decision-making. By analyzing data and learning from experience, AI systems can make predictions and decisions that are often more accurate and efficient than those made by humans.
