Task: ml-selective-deferral

Selective Deferral Under Subgroup Shift

Research Question

Design a practical selective prediction and deferral policy for high-stakes tabular decisions.

The task isolates one modular question: given a fixed base classifier, what acceptance / deferral rule best trades off selective risk, subgroup fairness, and overall discrimination?

Background

Selective prediction systems should be able to say "I do not know" when the classifier is uncertain. In high-stakes settings, that deferral can be handed to a human reviewer or a slower backup process. The benchmark studies whether a policy can:

keep selective risk low at a fixed target coverage,
avoid concentrating deferrals on one subgroup,
preserve AUROC as a confidence ranking signal, and
remain simple enough to run offline on modest compute.

Task

Modify the SelectivePolicy class in custom_selective.py. The rest of the pipeline is fixed: dataset loading, train / calibration / test splitting, base model training, and metric computation.

The policy receives calibration-time base-model probabilities and subgroup labels, then decides whether each test example should be accepted or deferred. You may implement a single global threshold, a learned deferral score, subgroup-specific thresholds, or any other compact policy that fits the interface.

Evaluation

The benchmark runs on four offline tabular proxies from scikit-learn:

breast_cancer
diabetes (binarized around the training-set median)
california (binarized around the training-set median)
madelon

Each dataset is split into train / calibration / test partitions. Subgroups are formed from a stable feature threshold so that worst-group behavior can be measured.

Metrics:

selective_risk_at80: classification error on accepted examples at 80% target coverage
worst_group_selective_risk: worst subgroup error on accepted examples
deferral_rate_gap: max subgroup deferral rate minus min subgroup deferral rate
auroc: AUROC of the acceptance score for predicting correctness

Baselines

confidence_thresholding: tune one confidence threshold to hit the target coverage
conformal_abstention: split-conformal abstention with a coverage target
learned_deferral: train a compact meta-model that predicts whether the base model will be correct
groupwise_thresholding: subgroup-specific thresholds as a stronger reference baseline

Practical Notes

This task intentionally uses datasets that are already available offline in the repository's scikit-learn package setup, so no shared package edit is required.

If you want the exact adult / ACSIncome / COMPAS / Law School datasets from the prompt, that would require a shared package-data follow-up, which I have not implemented here.

OOF validation gates the meta-model so it\n      is only used when it genuinely improves over raw confidence.\n\n    * **Accept / defer decision** (used for selective risk & fairness): per-\n      group quantile thresholds on the *base-model confidence* ensure stable\n      deferral rates that generalise from calibration to test.  Because\n      confidence comes from the fixed base model, its distribution is the\n      same across splits, producing near-zero deferral rate gap.\n\n    No existing baseline combines both: learned_deferral uses a meta-model\n    for decisions (unstable groups), groupwise_thresholding uses confidence\n    thresholds but has no learned scoring signal for AUROC.\n    \"\"\"\n\n    def __init__(self, target_coverage: float = TARGET_COVERAGE_DEFAULT,\n                 random_state: int = 0):\n        self.target_coverage = float(target_coverage)\n        self.random_state = int(random_state)\n        self.threshold_: float = 0.5\n        self.group_thresholds_: dict[int, float] = {}\n        self.meta_model_ = None\n        self.strategy_name = \"mlge_sd\"\n\n    # -- enriched meta-features -----------------------------------------------\n    @staticmethod\n    def _F(probs: np.ndarray, groups: np.ndarray,\n           X: np.ndarray | None = None) -> np.ndarray:\n        p1, p0 = probs[:, 1], probs[:, 0]\n        mx = np.maximum(p0, p1)\n        mg = np.abs(p1 - p0)\n        en = -(p0 * np.log(np.clip(p0, 1e-12, 1.0))\n               + p1 * np.log(np.clip(p1, 1e-12, 1.0)))\n        lo = np.log(np.clip(p1, 1e-12, 1.0)) - np.log(np.clip(p0, 1e-12, 1.0))\n        g = groups.astype(np.float64)\n        cols = [p1, mx, mg, en, lo, g, mx * g, mg * g, en * g]\n        if X is not None and X.ndim == 2:\n            for i in range(min(X.shape[1], 10)):\n                cols.append(X[:, i].astype(np.float64))\n        return np.column_stack(cols)\n\n    # -- fit ------------------------------------------------------------------\n    def fit(self, probs: np.ndarray, y_true: np.ndarray,\n            groups: np.ndarray, X: np.ndarray | None = None) -> \"SelectivePolicy\":\n        from sklearn.model_selection import StratifiedKFold\n\n        correct = (np.argmax(probs, axis=1) == y_true).astype(int)\n        feat = self._F(probs, groups, X)\n        conf = np.max(probs, axis=1)\n\n        # --- train meta-model with OOF validation ---------------------------\n        pipe = Pipeline([\n            (\"s\", StandardScaler()),\n            (\"c\", LogisticRegression(\n                max_iter=2000, solver=\"lbfgs\", class_weight=\"balanced\",\n                random_state=self.random_state, C=1.0)),\n        ])\n        n_sp = min(5, max(2, len(correct) // 30))\n        oof = np.full(len(correct), 0.5)\n        try:\n            skf = StratifiedKFold(n_sp, shuffle=True,\n                                  random_state=self.random_state)\n            for tr, va in skf.split(feat, correct):\n                p = Pipeline([\n                    (\"s\", StandardScaler()),\n                    (\"c\", LogisticRegression(\n                        max_iter=2000, solver=\"lbfgs\",\n                        class_weight=\"balanced\",\n                        random_state=self.random_state, C=1.0)),\n                ])\n                p.fit(feat[tr], correct[tr])\n                oof[va] = p.predict_proba(feat[va])[:, 1]\n            meta_auc = _safe_roc_auc(correct, oof)\n        except Exception:\n            meta_auc = 0.5\n\n        conf_auc = _safe_roc_auc(correct, conf)\n\n        if meta_auc > conf_auc + 0.005:\n            pipe.fit(feat, correct)\n            self.meta_model_ = pipe\n        else:\n            self.meta_model_ = None\n\n        # --- per-group CONFIDENCE thresholds (stable across splits) ----------\n        q = float(np.clip(1.0 - self.target_coverage, 0.0, 1.0))\n        self.threshold_ = float(np.quantile(conf, q))\n        self.group_thresholds_ = {}\n        for gid in np.unique(groups):\n            mask = groups == gid\n            if mask.any():\n                self.group_thresholds_[int(gid)] = float(\n                    np.quantile(conf[mask], q))\n        return self\n\n    # -- scoring (meta-model → AUROC) ----------------------------------------\n    def acceptance_score(self, probs: np.ndarray, groups: np.ndarray,\n                         X: np.ndarray | None = None) -> np.ndarray:\n        if self.meta_model_ is not None:\n            return self.meta_model_.predict_proba(\n                self._F(probs, groups, X))[:, 1]\n        return np.max(probs, axis=1)\n\n    # -- decision (confidence + group thresholds → fairness) -----------------\n    def predict_accept(self, probs: np.ndarray, groups: np.ndarray,\n                       X: np.ndarray | None = None) -> np.ndarray:\n        conf = np.max(probs, axis=1)\n        thresholds = np.array(\n            [self.group_thresholds_.get(int(g), self.threshold_)\n             for g in groups], dtype=float)\n        return conf >= thresholds\n\n    def calibration_summary(self) -> dict[str, float]:\n        s: dict[str, float] = {\"threshold\": float(self.threshold_)}\n        for gid, t in self.group_thresholds_.items():\n            s[f\"threshold_group_{gid}\"] = float(t)\n        return s\n"
