Convolution Vs Correlation

Convolutional Neural Networks which are the backbones of most of the Computer Vision Applications like Self-Driving Cars, Facial Recognition Systems etc are a special kind of Neural Network architectures in which the basic matrix-multiplication operation is replaced by a convolution operation. They specialize in processing data which has a grid-like topology. Examples include time-series data and image-data which can be thought of as a 2-D grid of pixels. The Convolutional Neural Networks was first introduced by Fukushima by the name Neocognitron in 1980. It was inspired by the hierarchical model of the nervous system as proposed by Hubel and Weisel.
