R · What Makes It Special: ResNet-50, the 50-layer version of the residual networks Microsoft Research introduced in December 2015, which learn residual functions with reference to layer inputs so that far deeper networks become easier to optimize; an ensemble of residual nets up to 152 layers deep reached 3.57% error on ImageNet and won ILSVRC 2015 classification, and the networks also won ImageNet detection and localization and COCO detection and segmentation.
