Convolutional Feature Maps Kaiming He. Visualizing and Understanding Convolutional Networks 1.1. Related Work Visualizing features to gain intuition about the net-work is common practice, but mostly limited to the 1st, In this article, we will explore how to visualize a convolutional neural network (CNN), a deep learning architecture particularly used in most state-of-the-art image based applications. We will get to know the importance of visualizing a CNN model, and the methods to visualize them. We will also take a look at a use case that will help you understand the concept better..
