Convolutional Neural Networks: Architecture, Mechanics, and Early Applications
To address the excesive parameter counts incurred by fully connected networks when processing images—where even small images can lead to hundreds of millions of parameters—convolutional neural networks (CNNs) were introduced. CNNs exploit two key structural inductive biases: translation invariance and locality. These enable_sparse, weight-share ...
