Proposes an e-process-based sequential diagnostic that detects misspecified PDE inverse problem fits earlier than standard discrepancy methods while providing anytime-valid type-I error control.
A new e-statistic enables anytime-valid sequential testing by betting on predictions from unlabeled data, with non-trivial power for binary outcomes even under inaccurate predictions and label or concept shift.
