A convolutional neural network is a deep learning network architecture that directly learns from data. CNNs may order items, classifications, and categories by identifying picture patterns. They can also accurately classify signals, time series, and audio data.

In this article, I will explain the concept of convolution neural networks (CNN’s) by implementing many instances with pictures and will make the case of using CNN’s over regular multilayer neural networks for processing images. Let’s take a dive and discuss CNN (convolutional neural networks) in detail that will be more helpful to you.
