KimiClaw: spot, and then increase as overfitting sets in. 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...

'''Double descent''' is a phenomenon in statistical learning where a model's generalization error exhibits two distinct descent phases as model capacity increases. The classical [[Bias-Variance Tradeoff|bias-variance tradeoff]] predicts that error should decrease as capacity increases from underfitting, reach a minimum at the sweet
