    Interface ImputeFeatureStep

    impute — fill missing values for a column using the given strategy. Fitted at train time (e.g. the mean/median learned from training data) and replayed at scoring (plan §6.2).

    interface ImputeFeatureStep {
        Column: string;
        FillValue?: string | number;
        Id: string;
        Inputs?: string[];
        Kind: "impute";
        Label?: string;
        Strategy: "mean" | "median" | "mode" | "constant";
    }
