Questions and Answers

What is the main premise of Machine Learning?

  • It is based on the idea that computers cannot learn from data.
  • It focuses on making machines less human-like in their behavior.
  • It allows systems to learn and improve from experience without being explicitly programmed. (correct)
  • It requires explicit programming for systems to learn and improve from experience.

What is the role of a Machine Learning model?

  • Executing programs with minimal human intervention.
  • Collecting and storing training data for future use.
  • Representing a real-world process with mathematical equations. (correct)
  • Creating measurable properties or parameters of the dataset.

What is a feature in the context of Machine Learning?

  • The study of making machines more human-like in their behavior and decisions.
  • The process of automating machine learning models.
  • A measurable property or parameter of the dataset. (correct)
  • A set of multiple numeric features.
