CS 451 Quiz 33
In a convolutional layer, the weights in the convolution filters play a similar role as the weight matrix W in a fully-connected layer
Given a 6x6x3 input image, what is the shape of the output of a convolutional layer that applies 5 filters of shape 3x3x3?
4 x 4 x 3
4 x 4 x 5
4 x 4 x 15
Unlike in a fully-connected layer, in a convolutional layer we don't have any bias parameters
What types of layers does a convolutional net typically contain? Check all that apply
Given the matrix [1 2 3; 4 5 6; 7 8 9], what is the output of a max-pooling layer with filter size f=2 and stride s=1?
[5 5; 8 8]
[3 4; 6 7]
[5 6; 8 9]
[1 3; 7 9]
A pooling layer has no parameters that need to be learned
If you start from the input layer and go from layer to layer deeper into a CNN, what typically happens?
The image size increases and the number of channels increases
The image size increases and the number of channels decreases
The image size decreases and the number of channels increases
The image size decreases and the number of channels decreases
