awesome-very-deep-learning is a curated list for papers and code about implementing and training very deep neural networks.

Deep Residual Learning

Deep Residual Networks are a family of extremely deep architectures (up to 1000 layers) showing compelling accuracy and nice convergence behaviors. Instead of learning a new representation at each layer, deep residual networks use identity mappings to learn residuals.

Papers

• Wide Residual Networks (2016) [orginal code], studies wide residual neural networks and shows that making residual blocks wider outperforms deeper and thinner network architectures
• Swapout: Learning an ensemble of deep architectures (2016), improving accuracy by randomly applying dropout, skipforward and residual units per layer
• Deep Networks with Stochastic Depth (2016) [original code], dropout with residual layers as regularizer
• Identity Mappings in Deep Residual Networks (2016) [original code], improving the original proposed residual units by reordering batchnorm and activation layers
• Inception-v4, Inception-ResNet and the Impact of Residual Connections on Learning (2016), inception network with residual connections
• Deep Residual Learning for Image Recognition (2015) [original code], original paper introducing residual neural networks

Very Deep Learning Theory

Theories in very deep learning concentrate on the ideas that very deep networks with skip connections are able to efficiently approximate recurrent computations (similar to the recurrent connections in the visual cortex) or are actually exponential ensembles of shallow networks

Papers

• Bridging the Gaps Between Residual Learning, Recurrent Neural Networks and Visual Cortex, shows that ResNets with shared weights work well too although having fewer parameters
• Residual Networks are Exponential Ensembles of Relatively Shallow Networks, shows that ResNets behaves just like ensembles of shallow networks in test time. This suggests that in addition to describing neural networks in terms of width and depth, there is a third dimension: multiplicity, the size of the implicit ensemble
