How many types of pooling layers in pytorch?

A)

One

B)

Two

C)

Three

D)

Four

Correct Answer : Two

Explanation : Pooling layers provide an approach to down sampling feature maps by summarizing the presence of features in patches of the feature map. Two common pooling methods are average pooling and max pooling that summarize the average presence of a feature and the most activated presence of a feature respectively.
