Certified Nephrology Nurse Exam

Question 1

In a typical Convolutional Neural Network (CNN) architecture, what is the primary function of the pooling layer?

To introduce non-linearity into the model. To reduce the spatial dimensions of the feature maps. To perform classification based on extracted features. To extract features like edges and textures from the input image.

Correct Answer:

To reduce the spatial dimensions of the feature maps.

Question 2

A data scientist is designing a CNN to classify high-resolution medical images. They are concerned about losing important information at the borders of the images during the convolution operations. Which technique should they employ to mitigate this issue?

Increasing the stride of the convolution. Using a larger pooling window. Adding a padding layer around the input images. Implementing a dropout layer after the convolutional layer.

Correct Answer:

Adding a padding layer around the input images.

Question 3

Which of the following best describes the role of the convolutional layer in a CNN?

To flatten the multi-dimensional feature maps into a one-dimensional vector. To apply a set of learnable filters to the input data to create feature maps. To reduce the number of parameters in the network through downsampling. To classify the input by connecting every neuron from the previous layer.

Correct Answer:

To apply a set of learnable filters to the input data to create feature maps.

Question 4

What is the main purpose of using the ReLU (Rectified Linear Unit) activation function in the hidden layers of a CNN?

To normalize the output of the layer to have a mean of zero. To convert the output into a probability distribution for classification. To introduce non-linearity, allowing the network to learn more complex patterns. To significantly increase the number of parameters for better feature extraction.

Correct Answer:

To introduce non-linearity, allowing the network to learn more complex patterns.

Question 5

In the context of a convolutional operation, what does the 'stride' parameter define?

The number of filters applied to the input volume. The number of pixels by which the filter slides over the input at each step. The amount of zero-padding added to the borders of the input. The size of the pooling window used for downsampling.

Correct Answer:

The number of pixels by which the filter slides over the input at each step.
