Neural Networks and Deep Learning Week 1 Quiz Answers Coursera

Question 1: What does the analogy “AI is the new electricity” refer to?

  • AI runs on computers and is thus powered by electricity, but it is letting computers do things not possible before.
  • Similar to electricity starting about 100 years ago, AI is transforming multiple industries.
  • Through the “smart grid”, AI is delivering a new wave of electricity.
  • AI is powering personal devices in our homes and offices, similar to electricity.

Question 2: Which of these are reasons for Deep Learning recently taking off? (Check the three options that apply.)

  • We have access to a lot more data.
  • Neural Networks are a brand new field.
  • We have access to a lot more computational power.
  • Deep learning has resulted in significant improvements in important applications such as online advertising, speech recognition, and image recognition.

Question 3: Recall this diagram of iterating over different ML ideas. Which of the statements below are true? (Check all that apply.) IDEA->CODE->EXPERIMENT

  • Being able to try out ideas quickly allows deep learning engineers to iterate more quickly.
  • Faster computation can help speed up how long a team takes to iterate to a good idea.
  • It is faster to train on a big dataset than a small dataset.
  • Recent progress in deep learning algorithms has allowed us to train good models faster (even without changing the CPU/GPU hardware).

Question 4: When an experienced deep learning engineer works on a new problem, they can usually use insight from previous problems to train a good model on the first try, without needing to iterate multiple times through different models. True/False?

  • True
  • False

Question 5: Which one of these plots represents a ReLU activation function?

  • Figure 1:
  • Figure 2:
  • Figure 3:
  • Figure 4:

Question 6: Images for cat recognition is an example of “structured” data, because it is represented as a structured array in a computer. True/False?

  • True
  • False

Question 7: A demographic dataset with statistics on different cities’ population, GDP per capita, economic growth is an example of “unstructured” data because it contains data coming from different sources. True/False?

  • True
  • False

Question 8: Why is an RNN (Recurrent Neural Network) used for machine translation, say translating English to French? (Check all that apply.)

  • It can be trained as a supervised learning problem.
  • It is strictly more powerful than a Convolutional Neural Network (CNN).
  • It is applicable when the input/output is a sequence (e.g., a sequence of words).
  • RNNs represent the recurrent process of Idea->Code->Experiment->Idea->….

Question 9: In this diagram which we hand-drew in lecture, what do the horizontal axis (x-axis) and vertical axis (y-axis) represent?

  • x-axis is the amount of data
  • y-axis (vertical axis) is the performance of the algorithm.
  • x-axis is the performance of the algorithm
  • y-axis (vertical axis) is the amount of data.
  • x-axis is the input to the algorithm
  • y-axis is outputs.
  • x-axis is the amount of data
  • y-axis is the size of the model you train.

Question 10: Assuming the trends described in the previous question’s figure are accurate (and hoping you got the axis labels right), which of the following are true? (Check all that apply.)

  • Decreasing the training set size generally does not hurt an algorithm’s performance, and it may help significantly.
  • Increasing the size of a neural network generally does not hurt an algorithm’s performance, and it may help significantly.
  • Increasing the training set size generally does not hurt an algorithm’s performance, and it may help significantly.
  • Decreasing the size of a neural network generally does not hurt an algorithm’s performance, and it may help significantly.
