Questions and Answers

What is the definition of a machine learning algorithm?

  • A method that relies on historical data to predict future attributes
  • A rule-based method for training and predicting new data
  • A program that learns from experience with respect to tasks and performance measures (correct)
  • A computer program that uses explicit programming to solve problems

Which concept is associated with machine learning, hyperparameters, gradient descent, and cross-validation?

  • Unsupervised learning
  • Semi-supervised learning
  • Reinforcement learning
