A Beginner's Guide to Deep Convolutional Neural Networks (CNNs) - Deeplearning4j: Open-source, Distributed Deep Learning for the JVM

Convolutional neural networks are deep artificial neural networks that are used primarily to classify images (e.g. They are algorithms that can identify faces, individuals, street signs, tumors, platypuses and many other aspects of visual data. Convolutional networks perform optical character recognition (OCR) to digitize text and make natural-language processing possible on analog and hand-written documents, where the images are symbols to be transcribed. CNNs can also be applied to sound when it is represented visually as a spectrogram. More recently, convolutional networks have been applied directly to text analytics as well as graph data with graph convolutional networks.
