Final Exam Answers – Deep Learning Fundamentals

Q1- For supervised learning, which of the following deep nets would you choose?

  • Autoencoder
  • Deep Belief Nets
  • Convolutional Nets
  • Restricted Boltzmann Machines
  • Recurrent Nets

Q2- Which of the following is true with respect to the training process of a deep net?

  • The Cost is the difference between the net’s predicted and actual outputs.
  • The training process utilizes gradients which measure the rate at which the weights and biases change with respect to the cost.
  • The objective of the training process is to make the cost as low as possible.
  • The training process utilizes a technique called back-propagation.
  • All of above.

Q3- True or False: With backprop, the early layers train slower than the later ones, making the early layers incapable of accurately identifying the pattern building blocks needed to decipher the full pattern.

  • True
  • False

Q4- For image recognition, which of the following deep nets would you choose? Select all that apply.

  • Autoencoder
  • Deep Belief Nets
  • Convolutional Nets
  • Restricted Boltzmann Machines

Q5- How does the Deep Belief Network (DBN) solve the vanishing gradient? Select all that apply.

  • It uses a stack of RBMs to determine the initial weights and biases, where the output of any RBM forms the input to the next RBM.
  • It uses a small labelled data set to associate patterns learned by the RBMs to classes.
