Deep Residual Learning for Image Recognition
Summary
The paper proposes reformulating deep layers as residual functions with identity shortcut connections, making it easy to train networks far deeper than before. Using this design, a 152‑layer ResNet achieved 3.57% top‑5 error on ImageNet, winning ILSVRC 2015.
- Residual blocks learn F(x) = H(x)‑x, adding the input back via an identity shortcut, which mitigates vanishing gradients.
- Identity shortcuts add no parameters or compute cost, yet enable training of networks with >100 layers.
- A 152‑layer ResNet outperformed much shallower VGG nets while using fewer FLOPs.
- Residual learning generalizes to other tasks (detection, segmentation) and datasets (CIFAR‑10, COCO).
Anyone building or researching deep convolutional models should understand residual connections to scale depth without optimization headaches.
