  • What is an AI Agent, and how does it differ from traditional AI systems?

    Answer:

    An AI Agent is an autonomous system designed to perceive its environment, make decisions, and act independently to achieve predefined goals. Unlike traditional AI, which relies on fixed rules or human intervention, AI Agents use real-time data, advanced reasoning, and adaptive learning to operate in dynamic environments.

    • Key Differences:
      • Autonomy: AI Agents self-govern tasks (e.g., inventory management), while traditional AI requires explicit programming 1.
      • Adaptability: They adjust strategies based on context (e.g., fraud detection in finance), whereas traditional systems lack flexibility 18.
      • Goal-Oriented Behavior: Prioritize objectives like cost reduction or scalability without constant oversight 1.

    Example: GitHub Copilot autonomously generates code, reducing developer workload, unlike static code-completion tools 1.

  • What is the difference between Artificial Intelligence, Machine Learning, and Deep Learning?

    Artificial Intelligence (AI) is the broad concept of creating machines capable of performing tasks that typically require human intelligence, such as understanding natural language, learning, reasoning, and problem-solving.

    Machine Learning (ML) is a subset of AI that focuses on the development of algorithms that allow computers to learn from and make decisions based on data, without being explicitly programmed for each task.

    Deep Learning (DL) is a further specialization within ML that uses multi-layered neural networks (often called deep neural networks) to model and learn complex patterns in data, enabling breakthroughs in areas like image and speech recognition.

    In summary, while all deep learning is machine learning and all machine learning is a part of AI, AI encompasses a broader range of technologies beyond just learning from data.
