Questions and Answers

In hyperparameter tuning, what is the purpose of a learning rate?

  • To control the number of epochs
  • To determine the size of each batch
  • To adjust the step size during optimization (correct)
  • To set the dropout rate
  • How does dropout contribute to regularization in a CNN?

  • By reducing the number of neurons in the network
  • By randomly dropping connections during training (correct)
  • By increasing the learning rate
  • By adjusting the kernel size
  • Which optimization algorithm is known for adapting the learning rate on a per-parameter basis?

  • Stochastic Gradient Descent (SGD)
  • Adaptive Moment Estimation (Adam) (correct)
  • Root Mean Square Propagation (RMSprop)
  • Mini-batch Gradient Descent
