CNN Pooling Operation Example

Pooling is an essential operation in Convolutional Neural Networks (CNNs) that reduces the spatial dimensions of feature maps while retaining important features. Let's break down the Max Pooling and Average Pooling operations mathematically using the given input tensor:


  • Kernel size: 2×2 matrix
  • Stride: 2

Max Pooling

Steps: The 2×2 kernel slides over the input tensor, computes the maximum value for each region, and forms the pooled matrix.

Average Pooling

Steps: The 2×2 kernel slides over the input tensor, computes the average value for each region, and forms the pooled matrix.
