    Question

    In the context of artificial intelligence (AI), which

    type of learning requires labeled data to train models?
    A Reinforcement Learning Correct Answer Incorrect Answer
    B Supervised Learning Correct Answer Incorrect Answer
    C Unsupervised Learning Correct Answer Incorrect Answer
    D Federated Learning Correct Answer Incorrect Answer
    E Deep Reinforcement Learning Correct Answer Incorrect Answer

    Solution

    Supervised Learning is a subset of machine learning where models are trained on labeled datasets. In such datasets, each input comes with a corresponding correct output (label), enabling the model to learn mappings between inputs and outputs. For example, in spam email detection, labeled data may include emails marked as "spam" or "not spam." The training process minimizes error by adjusting parameters to improve predictions. Common supervised learning algorithms include linear regression, logistic regression, support vector machines, and neural networks. The outputs can be continuous (regression tasks) or discrete (classification tasks). The reliance on labeled data ensures that supervised learning provides accurate models for tasks like image recognition and sentiment analysis. Why Other Options Are Incorrect: ·         Option A: Reinforcement Learning relies on an agent interacting with its environment and receiving rewards or penalties. It does not require labeled data but depends on reward signals. ·         Option C: Unsupervised Learning does not use labeled data; instead, it identifies patterns or structures in data. Clustering and dimensionality reduction are examples of unsupervised learning. ·         Option D: Federated Learning is a decentralized approach to training models across multiple devices without exchanging their data. It is unrelated to the use of labeled data. ·         Option E: Deep Reinforcement Learning combines deep learning with reinforcement learning techniques and focuses on learning policies from rewards, not labeled data.
