Convolutional Neural Networks
Neural network architecture optimized for image and grid-like data.
Why It Was Important
Building on the Neocognitron (1980), Yann LeCun successfully applied backpropagation to a neural network with convolutional layers (LeNet). By sharing weights across the visual field, CNNs drastically reduced parameter counts and preserved spatial relationships, becoming the absolute standard for computer vision.
