Dense Connections vs. Residual Paths: How DenseNet-121 Outperforms ResNet-50 in Brain Cancer Detection
A brain tissue slice is just 5 microns thick, twenty times thinner than a human hair. On such a slice, a pathologist looks for signs of a tumor: altered nuclear shapes, cell crowding, abnormal blood vessels. It is painstaking work, and two specialists can disagree on the same image.
