  4. Objective of AI Systems

    What is the main goal of developing Artificial Intelligence systems?

    1. To send spam emails automatically
    2. To replace all human jobs immediately
    3. To enable systems to learn and solve problems autonomously
    4. To only store large amounts of data

    Explanation: The primary goal of AI is to allow systems to learn and make decisions without constant human oversight. AI is not designed to instantly replace all jobs, only to store data, or to send spam emails. These other options either misrepresent AI's purpose or refer to narrow automation.

  5. Intelligent Agents

    Which of the following best describes an 'intelligent agent' in AI?

    1. A device that only stores data
    2. A website homepage display
    3. A program that senses its environment and takes actions to achieve goals
    4. A human performing calculations

    Explanation: An intelligent agent is a software component that observes surroundings and acts to accomplish objectives. Devices that solely store data do not act based on sensing or goals. A website homepage is a static display, and humans are not considered AI agents in this context.

  6. AI Evaluation

    What is the purpose of the Turing Test in artificial intelligence?

    1. To measure how fast a computer can run
    2. To determine if a machine can mimic human responses convincingly
    3. To check website security
    4. To calculate storage capacity

    Explanation: The Turing Test assesses whether a machine can act or respond in a manner indistinguishable from humans. It does not concern speed, storage, or website security. Other options describe unrelated computing tests.

  7. Strong AI vs Weak AI

    Which statement correctly differentiates 'strong AI' from 'weak AI'?

    1. Strong AI aims for true consciousness, while weak AI focuses on specific tasks
    2. Weak AI works without algorithms
    3. Strong AI does not exist in theory
    4. Weak AI can feel emotions, strong AI cannot

    Explanation: Strong AI refers to machines with true human-like awareness, which is not yet real, while weak AI is designed for specialized tasks. Weak AI does not have emotions; the option about algorithm use is incorrect, as both use algorithms. Strong AI is a theoretical goal and does exist as a concept.

  8. Explanation of Machine Learning

    How would you define 'machine learning' in the field of AI?

    1. A method for making phone calls
    2. A system improving its performance using experience or data
    3. A way to design websites
    4. A machine working only with mechanical parts

    Explanation: Machine learning involves systems that enhance their skills based on data or previous experience. Mechanical parts do not define learning in AI. Making phone calls and designing websites are tasks unrelated to the AI learning process.

  9. Common Algorithms in AI

    Which of the following is a commonly used algorithm in Artificial Intelligence?

    1. Decision Tree
    2. Echo Processor
    3. Layout Engine

    Explanation: Decision Trees are frequently used algorithms in AI for making decisions by splitting data into branches. Slide Show, Echo Processor, and Layout Engine are not recognized as AI algorithms; these refer to unrelated functions in software.

  10. Overfitting and Underfitting

    What does 'overfitting' mean in machine learning?

    1. A model learns training data too well but fails on new data
    2. A model uses only random guesses
    3. A model never learns any patterns
    4. A model is running out of memory

    Explanation: Overfitting refers to a model that performs well on training data but poorly on new, unseen data due to excessive memorization. Failing to learn any patterns is closer to underfitting. Memory issues and random guessing are not related to overfitting.

  11. Rule-Based vs. Learning-Based

    Which AI approach is based on a set of predefined if-then rules instead of learning from data?

    1. Statistical Learning
    2. Deep Learning
    3. Machine Learning
    4. Rule-based AI

    Explanation: Rule-based AI operates using explicit if-then instructions created by humans. Machine Learning, Deep Learning, and Statistical Learning all involve learning patterns from datasets instead, which is not the approach used by rule-based systems.

  12. Supervised vs. Unsupervised Learning

    In supervised machine learning, what is provided to the model during training?

    1. Encrypted internet files
    2. Only unlabeled data
    3. Input data with correct output labels
