Convolutional Neural Networks (CNNs) are the fundamental building blocks of modern computer vision, speech recognition, and even natural language processing applications. In this section, we are going to describe the convolution operator, how it is used in the signal analysis domain, and how convolution is used in machine learning.
Convolutional neural networks
The convolution operator
Signal theory gives us all the tools we need to properly understand the convolution operation: why it is so widely used in many different domains and why CNNs are so powerful. The convolution operation is used to study the response of certain physical systems when a signal is applied to their input. Different input stimuli can make a system...
