Learning

Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is a feature map?

πŸ’‘ Hint: Think about what happens to the image during the filter application.

Question 2

Easy

Name one parameter that affects the convolution operation.

πŸ’‘ Hint: These parameters dictate how the filter interacts with the input.

Question 1

What is the role of a feature map in CNNs?

  • To flatten images
  • To store filter weights
  • To represent detected features

πŸ’‘ Hint: Think about what feature maps are designed to do.

Question 2

True or False: Padding always decreases the size of the output feature map.

  • True
  • False

πŸ’‘ Hint: Consider the purpose of adding zeros around the input.

Challenge Problems

Push your limits with challenges.

Question 1

Create a diagram illustrating the convolution operation and the resulting feature map for a simple 5x5 image and a 3x3 filter.

πŸ’‘ Hint: Start with understanding what happens at each step of the convolution.

Question 2

Analyze how changing the stride from 1 to 3 would affect the output feature map size and interpret what that means for feature detection.

πŸ’‘ Hint: Think about how each stride value translates into filter positions on the input.
