Did not converge

WebTo reduce this discrepancy between theory and practice, this paper focuses on the generalization of neural networks whose training dynamics do not necessarily converge to fixed points. Our main contribution is to propose a notion of statistical algorithmic stability (SAS) that extends classical algorithmic stability to non-convergent algorithms ...

WebApr 3, 2024 · The optimization might not converge, either because the initial guess is poor or because the model is not a good fit to the data. SAS regression procedures for which this might happen include PROC LOGISTIC, GENMOD, MIXED, GLMMIX, and NLMIXED. For mixed models, several problems can occur if you have a misspecified model. WebNov 30, 2024 · Having categorical predictor levels (or combinations in interactions) without events can also lead to lack of convergence. That wasn't the case in the example data you showed here, but it happens in practice and it's a bigger problem when you use cross validation to choose the penalty.
