Webempirical risk from that of the corresponding population risk. 1 Introduction Understanding the connection between empirical risk and population risk can yield valuable insight into an optimization problem [1, 2]. Mathematically, the empirical risk f(x) with respect to a parameter vector x is defined as f(x) , 1 M XM m=1 L(x;ym): Web4 de dez. de 2024 · Our technique relies on a non-asymptotic characterization of the empirical risk landscape. To be rigorous, under the condition that the local minima of population risk are non-degenerate, each local minimum of the smooth empirical risk is guaranteed to generalize well. The conclusion is independent of the convexity. WebEven for applications with nonconvex nonsmooth losses (such as modern deep networks), the population risk is generally significantly more well-behaved from an optimization … rbs cyclery franklin
