One '+x' That Made 100-Layer Networks Trainable: ResNet Skip Connections

Resumo Executivo

• Residual blocks can improve deep networks by reducing the need for intermediate layers and improving the ability to learn the correct correction for input values.
• The +1 in the residual block formula keeps the gradient intact, allowing the block to learn the correct correction without vanishing.
• Residual blocks are particularly effective in deep networks, where the 2015 ResNet paper trained 152-layer networks, which were previously deeper than what worked before.
• The +1 keeps gradients healthy in modern LLMs, where skip connections are now everywhere and the 2015 ResNet paper trained 100-layer networks.
