Questions and Answers

What is the key characteristic of machine learning algorithms?

  • They rely solely on artificial neural networks
  • They become more accurate at predicting outcomes through explicit programming
  • They are a subset of traditional programming methods
  • They use historical data as input to predict new output values (correct)

Which of the following is NOT a milestone in the early history of machine learning?

  • The development of the Adaline model by Bernard Widrow and Marcian Hoff
  • Alan Turing's paper on the question 'Can Machines Think?'
  • Frank Rosenblatt's design of the first neural network called the Perceptron Model
