Double descent violates this prediction: after the classical overfitting peak, error decreases ''again'' as capacity grows into the highly overparameterized regime — often reaching values below the original minimum. The U-shaped curve of classical statistics becomes a W-shaped curve, or more accurately, a descent-ascent-descent trajectory that defies the textbook picture. The phenomenon was first systematically documented by Belkin, Hsu, Xu, Ma...
