OptionalKNumber of folds for kfold.
Fraction reserved as the locked final holdout that the experiment search never sees — scored exactly once on the promoted model (plan §8.2).
OptionalMajorityHow the trust verdict treats a classifier no better than always guessing the most common class (or one that
predicts a single class). Absent = 'enforce'. Recorded in the model's Lineage.evaluation at training time.
To be replaced by the Evaluation Protocol.
The validation approach.
OptionalTestTest fraction for train_test_split.
OptionalTimeColumn that orders the rows in time (e.g. MonthIndex) when the target is a forecast. Declaring it tells
Predictive Studio the model must be tested on later periods than it trained on; until that evaluation exists
(a rolling-origin backtest) the trust verdict is withheld with the stored reason "not evaluated as a forecast".
To be replaced by the Prediction Unit's Temporal Spec.
Validation discipline for a pipeline (plan §4.2 / §8.2). Defaults to a single train/test split with overfitting detection; k-fold and holdout are opt-in. A locked final holdout the search never sees is scored exactly once on the promoted model to produce the honest number.
