Week 03: Introduction to TensorFlow for Artificial Intelligence, Machine Learning, and Deep Learning Quiz Answers

Q1. What is a Convolution?

• A technique to make images smaller
• A technique to make images bigger
• A technique to isolate features in images
• A technique to filter out unwanted images

Q2. What is a Pooling?

• A technique to combine pictures
• A technique to make images sharper
• A technique to isolate features in images
• A technique to reduce the information in an image while maintaining features

Q3. How do Convolutions improve image recognition?

• They make processing of images faster
• They isolate features in images
• They make the image clearer
• They make the image smaller

Q4. After passing a 3×3 filter over a 28×28 image, how big will the output be?

• 26×26
• 28×28
• 25×25
• 31×31

Q5. After max pooling a 26×26 image with a 2×2 filter, how big will the output be?

• 13×13
• 56×56
• 26×26
• 28×28

Q6. Applying Convolutions on top of our Deep neural network will make training:

• Slower
• It depends on many factors. It might make your training faster or slower, and a poorly designed Convolutional layer may even be less efficient than a plain DNN!
• Stay the same
• Faster

Week 04: Introduction to TensorFlow for Artificial Intelligence, Machine Learning, and Deep Learning Quiz Answers

Q1. Using Image Generator, how do you label images?

• It’s based on the directory the image is contained in
• It’s based on the file name
• TensorFlow figures it out from the contents
• You have to manually do it

Q2. What method on the Image Generator is used to normalize the image?

• normalize_image
• rescale
• normalize
• Rescale_image

Q3. How did we specify the training size for the images?

• The target_size parameter on the validation generator
• The training_size parameter on the training generator
• The training_size parameter on the validation generator
• The target_size parameter on the training generator

Q4. When we specify the input_shape to be (300, 300, 3), what does that mean?

• There will be 300 images, each size 300, loaded in batches of 3
• Every Image will be 300×300 pixels, with 3 bytes to define color
• There will be 300 horses and 300 humans, loaded in batches of 3
• Every Image will be 300×300 pixels, and there should be 3 Convolutional Layers

Q5. If your training data is close to 1.000 accuracy, but your validation data isn’t,
what’s the risk here?

• No risk, that’s a great result
• You’re overfitting on your training data
• You’re underfitting on your validation data
• You’re overfitting on your validation data

Q6. Convolutional Neural Networks are better for classifying images like horses
and humans because:

• In these images, the features may be in different parts of the frame
• There’s a wide variety of horses
• There’s a wide variety of humans
• All of the above

Q7. After reducing the size of the images, the training results were different. Why?

• There was less information in the images
• There was more condensed information in the images
• We removed some convolutions to handle the smaller images
• The training was faster
