Questions and Answers

What is the purpose of monitoring overtraining during the training phase of a neural network?

  • To apply advanced gradient descent schemes
  • To stop the training at the appropriate time (correct)
  • To freeze the weights
  • To adjust the learning rate
  • Which technique can help moderate overtraining in a neural network?

  • Implementing a linear decay for learning rate
  • Applying regularization methods (correct)
  • Using exponential decay for learning rate
  • Freezing all the weights
  • What does over-fitting in a neural network indicate?

  • The learning rate is too high
  • The network is learning spurious patterns in the data (correct)
  • The network is underfitting
  • The network is undertrained
