This Github repository explains the impact of different activation functions on CNN's performance and provides visualizations of activations, convnet filters, and heatmaps of class activation for easier understanding of how CNN works.

Visualizing what ConvNets learn

This Github repository showcases the activations of a Convolutional Neural Network (CNN) used for classifying images of cats and dogs.

The purpose of this project is to provide a detailed explanation of how CNNs work, specifically how the different activation functions impact the CNN's performance and ability to classify images. By visualizing the different activations, convnet filters and heatmaps of class activation in an image of the CNN model, I aim to make it easier for developers and machine learning enthusiasts to understand how a CNN works under the hood.
