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
