We show, via simulations, that tests of hypothesis about the generalization error using those new variance estimators have better properties than tests involving variance estimators currently in use and listed in The minimization algorithm can penalize more complex functions (known as Tikhonov regularization, or the hypothesis space can be constrained, either explicitly in the form of the functions or by adding constraints We demonstrate that this valuation may be used to select training sets that improve generalization performance.

This could lead to gross underestimation of the variance of the cross-validation estimator, and to the wrong conclusion that the new algorithm is significantly better when it is not. McCullagh, P. M.

Poggio, and R. Alex Minnaar, NLP Software EngineerWritten 75w agoGeneralization usually refers to a ML model's ability to perform well on new unseen data rather than just the data that it was trained on.

As a result, measurements of prediction error on the current data may not provide much information about predictive ability on new data. The second condition, expected-to-leave-one-out error stability (also known as hypothesis stability if operating in the L 1 {\displaystyle L_{1}} norm) is met if the prediction on a left-out datapoint does not Save your draft before refreshing this page.Submit any pending changes before refreshing this page.
